Things are heating up thanks to Nazis, Hitler, and Alex getting into trouble - as usual.

Even if I really, really enjoyed this book, just like with the previous stories, there was one thing that kept bothering me. Alex has this protection rune thingy. It's supposed to protect him and Sorsha, but the thing gets (conveniently) put out of commission to raise the stakes in the book.

This felt like a pretty low trick to make things more risky for Alex and Sorsha through out the book, because instead of actually fixing his rune - first thing, first moment he gets a chance - Alex runs around and is in real danger instead.

While I do get why the book's been written this way, I did find it stupid and more annoying than what I would have liked. It is such a small thing, yet it paves the entire foundation for why the stakes are as high as they are through out the book.
If Alex had found time to fix his protection rune this whole issue of mortal danger probably wouldn't have existed.

But oh, well... It's still a really enjoyable book and I adore the narrator and Alex.
Can't wait for book 10!

As in each previous book, Alex is dealing with more than one single case, although, tbh, this time he didn't get into trouble by himself *laughs*

Donovan came asking for help, and they went to Europe to rescue a rune writer. They managed to complete their mission and come back in one piece.

But from then on, well... Nazi spies, an übersmenche that is covered in runes, unexpectedly valuable musical instruments, murder and mayhem. Yeah, almost a usual week for Alex. *grins* Except, this time, he gets badly hurt, and he does something that he shouldn't. Iggy is worried about him, with reason and OMG! How will I live until the next book comes?

Because, that ending? That ending left me wanting more and right now! ~sighs~

A wonderful escape, as usual!

Mr Willis has yet again woven a tapestry of magic, detective work, and government secrets into a wonderful story! The ending has me waiting on pins and needles for the next of Alex’s adventures… if there is a next time!

I like Lockabee and the mischief he gets into, though he doesn't give himself enough down time to recuperate or heal. With all tge plots he keeps disrupting that the Third Reich are trying to do, he is painting a target on his back. Iggy is getting concern with him also. Narrator is Still doing a Fantastic job with the various characters voices and the entire storyline.

Hidden Voices (Arcane Casebook Book 9) continues the strengths and weaknesses that have defined the series from the beginning. The setting remains the primary draw: a magical noir detective story in a stylized 1930s that blends arcane mechanics, smoky back rooms, and political intrigue. That combination is inherently appealing and still works. The narrator’s voice, the atmosphere, and the historical texture give the books a personality that is distinct from other urban fantasy.

The limitation is the same one the series has never resolved. The storytelling leans heavily toward telling rather than showing. Emotional reactions, relationship developments, and moments that should have dramatic weight are described rather than enacted. Scenes often summarize what characters feel or decide instead of letting those shifts emerge through dialogue, behavior, and consequence. The result is that the story is consistently interesting but rarely vivid. It moves, but it does not deepen.

This volume also contains choices that feel implausible within the story’s own logic. The most obvious is the protagonist spending much of the book without a shield rune, despite multiple assassination attempts, ongoing danger, and his own established familiarity with defensive magic. It is difficult to accept that he would continue operating unprotected when the threat is so clear. The decision seems written to maintain tension, but the tension is artificial because the character would not reasonably behave that way.

Even with these issues, the series remains enjoyable. The concept of a noir arcane detective is strong enough to carry the narrative, and the world is pleasant to return to. Hidden Voices is good, not great. The atmosphere works. The ideas work. The execution holds it back. I like reading it, and I will continue reading it, but I often find myself wishing it would slow down, dramatize its beats, and let the story be lived rather than explained.

I enjoyed this book even after breaking it into two sections punctuated by a long period of other things. The Sorsha / Alex romance is starting to grow on me, especially when given a chance to see how Sorsha feels about it. She makes no attempt to hide the desire and possessiveness she feels towards Alex.

Alex meanwhile seems somewhat distanced from everyone he is usually tight with. This puzzled me until about the last third of the book when I think I figured it out, and then had it confirmed by the ending. The thing that carries you through this distantness is that there is quite a bit of action. Alex gets a chance to try his hand at the spy game both forign and domestic and frankly he doesn't come out of it too well.

In fact Alex spends a suprising amount of time convalesing in this book. The scaling power levels of both heros and adversaries are driven home by the number of times Alex failed to be prepared for what was coming. Now that I think about it, this lack of foresight was also obvious and can also be explained by the ending of the book.

The ending. I've mentioned it a few times now and I'm going to have to tiptoe to not give away any spoilers. However, Alex has managed to work himself into a bad situation and he'll need all sorts of help to get back out. I am very curious to see how it is displayed in the next book, and having some personal understanding I'll pay close attention. The ending leaves no doubt that Willis needs to address the fallout right away.

Also, Dan Willis gave my wife a pin for me, and now it rides on my OG BattleStar Galactica jacket. Thanks Dan!

Fantasy Noir at its very best...

There is something so refreshing about picking up a book and getting exactly what you expected and being surprised at what you didn't expect. Dan Willis is a craftsman. Every book in this series is well written, properly edited and provided with the necessary forethought to close up any plot holes that often come with writing fantasy and a unique magic system.
Each book builds upon the previous. However, they are all unique. As a reader you can dive in to any book, be it 1, 5, or 9 and still enjoy the story. Although, I would most definitely recommend starting from the beginning.
The cast of characters has grown as expected, and from time to time each has a brief cameo, if not a major role. It's like an old friend coming to visit. Each character is well fleshed out. None more than Alex, Iggy, Sorsha and Detective Pak who form the heart of the cast.
The runic magic system is flawless. Willis has obviously made a great effort to craft each rune in such a way that it is believable. Furthermore, he takes the time to explain any contradictions that do occur, as is evidenced
in this very installment. The alchemical and sorcerer magic systems are equally well executed.
Overall the entire series is humorous, mysterious, thrilling and just plain fun.
I would highly recommend this series to any fantasy reader regardless of your sub-genre leanings.

Von Trapp Me Outta Here

ArcaneCasebook9

The series is building to a big finish.

Alex met the remnant of the US Intelligence Agency, when he went to Washington. Bill Donovan told Alex who had turned Zelda Pritchard’s servants into alchemical agents; and who Alex needed to be wary of. Alex knew Bill Donovan was one of those people, but all he can do is try to be better prepared.

Because, Alex knows a lot more of the players than Bill Donovan suspects; and with the creation of Limelight, and the mind control construct, and just the sheer volume of people striving to better their understanding of runic applications, more and more instances of ruthlessness are coming.

Alex just has to stay ahead of the curve, while falling in love with a woman who attracts interest. Notoriety is not Alex’s friend. And, his skill set plus his success rate is giving all sorts of people ideas…

Headed to the Limelight

Just finished Hidden Voices, Casebook 9. Can only state my disappointment ... that I now have to wait for Casebook 10 for my next Alex fix. Musicians, alchemists, FBI agents, spies and nazis. All in the normal uneventful life of detective extraordinaire Alex Lockerby. Not to forget his cadre of friends, always watching his back as his enemies try to 'rune' his day. Alex is special and talented but almost too human and, dare we say, protective of those he loves. Will this ultimately be his undoing? Who knows. Only way to find out is to read on. If you are just now being introduced to Alex, I would suggest going to the beginning, Arcane Casebook 1 and meet Alex on what is truly a wild ride.

Good fictional works are weakened far too often by a myopic authorial focus on the plot: characters begin to serve it and morph into cardboard cutouts. Dan Willis ably prevents this from happening in "Hidden Voices"by running two mysteries side by side and switching from one to the other. Alex, Sorsha, Danny, and crew get plenty of time to interact in the transition scenes. Willis knows that his readers like these folks and enjoy spending time with them. I do have one complaint. Sorsha doesn’t like being called “Doll”. Alex knows this but does it anyway to tease her. Please, once or twice in a given novel is enough. After the fifth time, I began to fear that she would lose it and freeze him solid — even though he deserved it at that point.

Arcane Noir Delivers Enjoyable Read.

I stumbled upon this 9 book series through an Amazon suggestion. I am delighted that I gave the first book a chance as I became hooked from the first paragraph. I really enjoyed the character interactions and the way the stories within each book unfold. I enjoyed the time frame these exist within as well My only question is are we ever going to get to read about the remaining sorcerers? We got 2 of the New York 6. I am eager to read the next book in the series when I arrives. These have been great reads.

high quality entry

I so look forward to new books in this series. They are drop everything and get after it. This is no exception. The only disappointment was that in most other books, Alex discovers some new runic ability or techniques and there really wasn’t one this time.

I imagine the next book will deal with the fallout from the ending of this one and probably swing back to the larger conspiracy.

Mr. Willis just keeps getting better, and all of his many faithful readers appreciate it, I’m sure.

This latest story about Alex Lockerby and his colorful cohort has them battling the (gasp!) NAZIS, who have their own stable of powerful magicians, and who are dead set on wreaking havoc around the world. It’s up to Alex and his friends to stop them.

Another wild ride, with friends new and old, that definitely doesn’t disappoint. Can’t wait to see what happens next!

hidden voices

Hidden Voices was another amazing story. I have enjoyed watching the development of the characters. From their love affairs, & taking harmful stuff. I also like the introduction of the SS into the story. Can’t wait to see where the story goes, now I have to wait for the next story, from Arcane Caseboook, & the phoenix series with Lt Pak. I highly recommend these series. PS: Mr Willis, what is the release date for more of your books?? 😊

Alex never dissappoints

Alex Lockerby is a great hero, intelligent, brave, loyal and just a bit flawed. This time working with the government to fight the Nazis. Add to it a local case with Danny Pak and the death of a mandolin player and you have a great story. I love the cast of characters but wish the romance with Sorcha was moving along faster.

Hopefully Iggy will come through.

Another solid Arcane Casebook entry

Let me paraphrase something I read on an urban fantasy reddit sub to describe the Arcane Casebook series "...if Jim Butcher and Dashiell Hammett had a book baby, this series would be the result". I like this series because I'm a fan of UF detective novels and because they aren't overly boated with a lot of characters and subplots. It's a good, solid grimnoir story.

What a ride!

What else can I say about finishing another book in the Arcanse Casebook series? Other than grabbing the only other book related to it (curse of the Phoenix, in the Arcane Irregulars side series) to read while I eagerly await the next in either series to be written and/or published? It's really nice to run into someone whose writing is so delightfully enthralling...and just plain fun!

Nazis, a Stradivarius mandolin and a murder

Dan Willis takes our heroes one step closer to a second Great War in his world of runewrights and sorcerers.
Along the way, Alex Lockerby gets to work with Wild Bill Donovan and gains a Nazi nemesis all his own. And go mano y mano with an honest to God Nazi Übermensch, who’s not so über after all. Throw in a real whodunit to solve and Willis delivers another enjoyable entry in his Arcane Casebook series.

So very good

Alex is at it again. But this time he has some major enemies who want him dead.
A trip for the government starts a chain of events that introduces Alex to a German Superman.
And trying to help Danny Pak is just frosting on the cake.
I loved this latest addition to the series and hope you enjoy it too.

Arcane Casebook series is addictive!

I am a big fan of this detective series that incorporates magic as something everyone knows about. Setting it in a bygone era reminiscent of Sam Spade is perfect, and I love that the cases take real ingenuity to solve. Try it / you will be hooked! Dan, hurry up with Book 10!!!!

Hidden meaning

I really enjoyed this story from the Arcane Casebook series. I enjoyed Mr. Willis’ writing and have gotten next to nothing done today while I read the book. I recognize the reference to hidden voices but did not understand why it was used as the title. I will definitely keep reading this series.

I enjoyed reading "Hidden Voices" and endeavored to make the book last as long as possible! The book was one of the best of the Arcane Casebook series! I look forward to the next book! I hope it does not take long. The story was full of action and moved along quickly. I lost some sleep staying up to read!

Dan Willis has another winner! Keep writing!

It's 1939 and Hitler is making his move. Last book Alex was recruited by Wild Bill Donovan and he's sent into Austria to rescue a talented alchemist from the Nazis.
On the home front Alex is assisting the police with a murder investigation.
Between the case and trying to stay out of the Nazi assassins' crosshairs makes for quite an exciting story

Absolutely Wonderful Series!

I've rated every book in this series, but this is my first review. I consumed these books over the course of a few weeks, and every entry made me crave more. Sherlock Holmes plus magic plus 1930's detective equals a winning combination! Start at the beginning with "In Plain Sight," and you will not be disappointed.

Spies and Gypsies

Willis’ Runewright detective returns in his latest Arcane Casebook novel to fight a Nazi übermenschen through the streets of 1939 Manhattan, while also working with NYPD Lieutenant Pak on a case of a Romany musician fatally bludgeoned with a mandolin.

Note: Ends with a cliffhanger, and the next book isn’t yet published.

Recommended.

The quality of this series has improved over the last few books and this was an excellent addition to the series. I liked that the author has used earlier deus ex machina plot devices in this book to solve the storyline and it is set up nicely for the next book in the series. Looking forward to reading number ten!

Hidden Voices

Hidden Voices sees Alex Lockerby square off with the Nazis once again. This time more direct than ever. In addition to juggling a murder and a stolen mandolin, Alex has a lot on his plate. But as always the clever detective finds a way to pull through. Dan Willis really has a talent for this and struck gold with the Arcane Casebook series!

Still going strong!

It’s very rare that a series doesn’t peter out at some point. I thought this was starting to happen with this series but book nine came back with a vengeance! Focusing mainly on the overarching storyline (if you read all the books in the series, you know what I’m talking about). On to the next!
