The Accidental Detective

Rate this book
Loner. Lawbreaker. Bad girl. These all describe Hannah Tree, but she never expected to add private detective to the list...

Serving a minor prison sentence isn’t the usual training for becoming a private investigator. But Hannah’s new mentor Gloria Starr, a statuesque trans woman, convinces Hannah to turn her obsession with justice into a business.

Hannah’s first case is simple. A routine check on a client’s spouse, a judge whose wife is worried about him. Gloria suspects he might be a member of the mysterious “Friday Night Club”. Everything changes when Hannah sees her father entering the club.

Something sinister is happening that not all the members know about. Determined to uncover the truth, Hannah discovers that some secrets are deadly. But she’s waited her entire life to bring her father to justice, and she’s not going to stop now. Even if it's the last thing she'll do.

Serving time for a minor offence, Hannah Tree meets the flamboyant Gloria Starr in a mental health facility. When Gloria offers Hannah a job and a place to live, she also suggests a second career: investigator. But Hannah's first case, a simple surveillance, leads her into a dangerous world where she'll need all the help her newfound friends can give.

This was a rollercoaster ride of a story! Hannah is so compelling, and the rest of the cast is just as amazing. I couldn't put the book down, and so, I'm writing this review after midnight.

Be warned, this is a thriller. Some scenes are not for the faint of heart.

Whoo this was a good book, a disturbing yet thrilling ride with a lot of physical violence along the way. This is an Australian author and I have no idea how the justice system works over there so this is rather an eye-opener for me, I actually thought this was yet another american crime book as there was mention of dollars and senior sergeants, although I havent't heard that in american books!

Young uppity Hannah Tree is in some sort of mental place and meets a transgender gal called Gloria Starr who runs a sort of theatre cum dance club for other transgender men. I have no idea why either of them is in there but they are both let out and Gloria gives Hannah her phone number and says look me up. She does and that's when she decides to add becoming a detective to her skillset as she's discovered that her father, who was into raping her when she was quite young, was hanging out at a place full of men who liked both girls and boys and violence and even murder seemed rife amongst them, and add other grizzly things which explains how some youths living on the street were missing...

Hannah garners a team around her of other street misfits like herself and they work surprisingly well. There are sub stories amongst this but you can read them for yourselves but warning there is a far bit of violence in this story and the ending is a tad horrible. But the ending does take a turn for the better as Hannah turns out to be rather good at this detection lark and thinks she will carry on being a private detective and saving young people's lives into the bargain.

Good book but not for the faint hearted as the descriptions of violence leave a bit to be desired but it shows how Hannah is used to fighting for her life on the streets and this is just a continuation of that, plus she really does deep down care for those young people who are living on the streets because it is better than home, and better in some cases than living in a sheltered place for the homeless... I really liked the misfits she gathered around her who went to amazing lengths to help her find the murderers of young people. I would like to read more of Hannah Tree's escapades! In fact I've just bought all of the series on Amazon!!

3.5 stars. While I did enjoy the adventures of Hannah Tree, I felt a little off balance throughout the whole book. I could not orient myself to time and place, and it took quite a while for me to realize it was neither an American or British place. The subject matter is a little disturbing, but it is not a serious police procedural. Hannah is a street kid from a wealthy family who finds herself in a psychiatric hospital ordered by the court. There she meets Gloria Starr, a flamboyant drag queen trans wannabe who gives her a job and a place to stay upon her release. Hannah takes on cases to get justice for those unable to do it themselves. She assembles a rag tag crew, and work together. This was a little over the top...Hannah is able to figure out what is happening to some street kids, what a homeless shelter has to do with that and with a Gay Bar that has evolved into something more sinitster and break up a pornography ring, all the while being kidnapped twice, beaten and left for dead. Too much is going on for this to be even a bit believable.

I generally don't read Australian authors because Australian settings don't usually appeal to me, but I picked this book up by mistake and I'm really glad I did. It was a refreshing change and had a genuinely original storyline.

The characters were fun, endearing, and easy to connect with. The author provided enough detail for me to form a clear picture of each character and really visualise them within the story. I could easily picture the theatre and the characters on stage, and Gloria was definitely a standout for me.

Although the story contained some heavier subject matter, the author handled it with tact and descriptive detail without becoming excessive or uncomfortable. The writing was well done, the pacing was consistent, and the small amount of romance was well placed and didn't overwhelm the main story.

Overall, this was a fun and entertaining read. I would happily continue with the series, particularly if the main characters remain involved. A pleasant surprise and a book I'd recommend.

A solid story with compelling characters and unexpected twists and turns. The plot was huge and it was a lot of detail that kept getting bigger and bigger. I did like the ending.

Hannah, the accidental detective, was shaped by abuse suffered as a child. She developed into a hard-shelled young woman who would as soon spit at you than take any pity. Despite her experience living in the dregs, she still has a little naivety about how things work outside of her view of the world. She is literally saved by Gloria, a transgender force of a woman, who sees something in Hannah and decides to befriend her. Under Gloria's mentoring, Hannah begins to transform into someone who begins to learn that she can trust and that it takes a team to really win.

Oliver kept me engaged with the story despite the rather large plot. She managed to tie up all the various strings which is impressive. I would read her next in the series.

Many twists and turns

This book was unlike any other book I've ever read. After reading it for a few chapters I decided it wasnt "my mind of book" but i'd pick it up and read more. When I got to the half of the book I decided I'd read it to the end. And I did! The main character was in a psychiatric facility and was hiding her time to be released. Then she met various people, the main one being a transvestite who asked her for help in finding her daughter because she figured she could find her because she had spunk. Long story with many characters but definitely worth the time to read. Get it, read it!!

A Gripping Read

I wasn’t sure if I would like this story. But…. I did. Oliver got my attention quickly and once I figured out what was happening, I had difficulty not continuing to read, even when I had lots to do. This is a good read and one I certainly recommend. Thanks Deirdre Oliver.

Captivating

Hannah Tree, my, what a chip this young lady has on her shoulder! Abused as a child, followed by years on the street is not the way to grow up. Happenstance forges a path for her as she is released from custody, she finds a molds a new life and the downtrodden are all the better for it. It was a surprise to me to enjoy so much about this novel!

Wow. Will definitely be reading the whole series. Hannah is such a fun character, with her whole band of helpers who play such niche roles in her investigation. My only qualm was the romance between Hannah and Nick was very cliché.

This was fun. A different kind of detective novel; a little gory at times. But I liked the fun characters.

At first I did not like the Accidental Detective because of the unfamiliar pattern of talk (to me). Finally got into the rhythm of it . Thoroughly enjoyed this mystery with colorful relatable characters.
Very often made the mental error of thinking of the book's title being The Accidental Tourist a favorite movie of mine starring William Hurt
