Millie's Cruise Ship Mysteries: Tiki Hut Tragedy

Cruise Director Millie Mysteries #6

by Hope Callaghan

Cruise Director Millie Mystery Series is the new spin-off series from the wildly popular Millie’s Cruise Ship Cozy Mysteries by Author Hope Callaghan.

When a passenger on a floating tiki bar excursion goes overboard, Millie suspects one of the woman’s fellow foodie contestants has an appetite for murder. With the Siren of the Seas heading for port, can she solve the case before a killer disembarks undetected?

Recipe Included!


After a busy season cruising the icy waters of Alaska, the Siren of the Seas returns to its tropical homeport in sunny Miami. Group bookings are at an all-time high, and cruise director Millie Armati barely has time to catch her breath before the next wave of passengers board the ship.

Among them is a boisterous bunch of competitive eaters known as the Belly Busters, famous for traveling coast to coast devouring everything from chili to cheesecake in high-stakes food showdowns. But behind bottomless appetites and dynamic personalities, tensions simmer—especially toward the three contestants who always seem to come out on top.

When the group books a private excursion aboard a floating tiki bar, Millie reluctantly agrees to help coordinate the event. But as she watches the hut drift from shore, an ominous feeling creeps in...and her worst fears are realized when the tiki hut returns to shore—minus one passenger.

The death, a drowning, is quickly ruled an accident, but whispers of foul play ripple through the decks. Determined not to let a potential killer slip away, Millie dives into the mystery—and discovers not everything is as it seems.

Can our cruise ship sleuth expose the truth and dish out justice before the Belly Busters disembark? Or will a contestant with an appetite for murder get away scot-free, leaving Millie hungry for answers?

Who Wins & Who Loses their Life?

Hope Callaghan is an excellent story teller! As usual Millie's Cruise Ship series is a wonderful blend of mystery, friendship, humor and love.

In the Tiki Hut Tragedy, Millie and friends welcome past elite passengers, first time cruisers and the competitors of the Belly Buster group. The Belly Buster's is a group of women contestants in a food-eating competition. A lot was up for grabs with these ladies, they took the word competitors to a new high and argued continuously with each other.
It was not a surprise when during a stop at one of the islands, with the boisterous ladies on a Tiki Hut excursion an accident happens. Millie who was also off ship and saw the tragedy happen was not sure it was an accident. With the help of many of her ship mates working friends, they work together to help Millie catch the killer.
Tiki Hut Tragedy is filled with mystery, mayhem, friendship, humor and love. As usual with a Hope Callaghan story, I couldn't put down the book and read straight through. This was an amazing book, like all of Hope's series, I have read every book she has written.
If you want a wonderful cozy read, you need to scoop this one up!!

Looking for a comical page turning mystery? Then Sail the Seas with Siren of the Seas, Millie and friends and watch the mayhem with boisterous competitive foodie contestants and frenemies - the Belly Busters unfold. Yes, their names are descriptive and their childish antics worse - Dixie the Destroyer, Wendy or Wolf, and Hannah the Heavyweight. Hope Callaghan is a gifted succinct mystery writer. The reader is immediately drawn into the drama, sorting through red herrings and foreshadowing, and predicting the resolution. As a Michigander retired educator, I learned about cruising near the Bahamas, plus the ins and outs of food eating competitions. Recipe for Annette’s Gourmet Lobster Roll included.

Cruising with Belly Busters!

Millie has an interesting group of ladies on board for this cruise - the Belly Busters, a group who compete to see who can eat the most! They’re a unique group and fun to watch until one of them dies! The death is ruled an accident, but Millie has other ideas and decides to investigate further. There’s stomach relaxing pills, events to practice stretching their stomachs, and more. Can Millie figure out who killed the reigning winner before they dock in Miami, where the actual contest takes place? I received a free advance copy of this book and write this review voluntarily.

[Leslie Ferrari]

Another fun adventure with Millie and the gang. The ship has repositioned back to the Caribbean from Alaska (the setting for the last couple books) and the cruise has a group of demanding competitive eaters on board. After a tiki hut bar cruise excursion, there is one fewer in the group. The defending champion is dead after an incident on the excursion; was it a tragic accident, or murder?

There is a malfunction with the ships propulsion which is a cliff hanger. In addition, we get a tease that the next book with be a cross-over with the Garden Girls series, sure to be a fun read.

Tiki Hut Tragedy

As much as In enjoy cruising I think if I ever see a tiki hut excursion on the list I will avoid it. This book was written in a way that was very interesting & intriguing. Quite the mystery to solve. The characters all come together to create a unique experience that makes you want to keep reading and learning how to solve the mystery. Very well written!

Christian Cruise Cozy

Millie and her friends on the crew find the death of a passenger suspicious and can't let it go. Ms. Callaghan spins her tale of a curious woman with talented friends who try to fly under the radar while piecing facts together. I enjoyed the tale and recommend it for a fun relaxing read.

[Tony T Adams]

Another great book.

I really enjoyed this one another great read. I especially like to reading about the ports of call, I have been to the Grand Turk and the privately owned island. I have cruised the Caribbean many times and enjoyed every trip. I have already ordered your next book. Love all of them.

Millie’s Cruise Ship Book 6

Another fun cozy mystery with Millie & the gang. This series is filled with good characters & interesting storylines. They are fast paced, no gore, no bad language, a little romance but no sex scenes & they are easy to read which makes them perfect to read while relaxing.

[Richard Cowart]

Continued excellence

As Siren of the Seas is back in the Caribbean one of the groups is Belly Busters a food eating group preparing for a competition. They are a rambunctious group causing mischief and being obnoxious. The new pastor feels all alone and Millie takes him under her wing to help him adjust. When one of the Belly Busters dies Millie and gang go investigating.

[Norma Heatherly]

Ms Callaghan has done it again.

This was truly a lovely story. This was a who dunning mystery, or did someone actually do it. Millie likes to think so, at least. As always, this kept my interest throughout. Keep up the amazing work.

[Judy G Spivey]

This one will keep you guessing.

The Siren of the Sea, Millie and her crew are back in their warm waters. A group of competitive eaters keep things jumping on this cruise. Then there’s the drowning was it murder or not. One of the best Millie books.

[Darlene]

I love the Millie Cruise Ship Mysteries

It is always fit to join Millie and the crew for a cruise. I love reading about all the places they go and trying to figure out the mystery. I enjoyed this one and was not sure who the culprit was until the end.

[Conni]

Back in the Caribbean!

Once again Miss Hope has done it!! Once you pick up this ook you'll read to the end! The characters come to life and the plot keeps you guessing! Can't wait for book 7!

[Alan Eilers]

lighthearted fun

This is a light fun book. I think Millie would have figured out about Astrid’s disguises much faster than what was portrayed in this book. Otherwise a light fun read.

[Amy Gill]

Hooray for Millie and her team!

Millie and her "detective" team have done it again. This was a tough one with the guilty party hiding behind a disguise. New crew members aboard ship add to the adventures. All in all a most enjoyable read. Thanks, Ms Callaghan!

[Polina Posner]

Food eating contest competitors get more than they bargained for

When a food eating contest competitor ends up dead during a routine excursion, Millie and the gang need to figure out if it was an accident or something more sinister.
Wonderful clean series with whodunits galore

[Ruth Turner]

Enjoyable

An enjoyable mystery with Millie and her friends. We meet an interesting new characters and troubling technology. The plot, motives, and characters are easily understandable.

[Marion Moxhay]

It's been a long time since I've read a Millie mystery. They're such fun, with great characters. I love the cross over elements when we get them, especially if you're a fan of all Hope's cozy mysteries.
Great to be back on board.

[Barbara]

I was sad to see that this is the last book of the series until September. I will miss reading about what Millie and her crew get up to. This was an interesting story full of suspects and eating loads of food. Strongly recommend this series and this book.

[DEBRA KAASTRA]

Some eat, some peay, most love....

Millie must "stomach" a group of competitive eaters and find out why things aren't really as they seem. Everyone wants to win but someone is really a big loser

[Ginny Daly]

Great book

Lots of good people & suspense about this cruise ship and the people who travel around the world for the lives

[fran zimmerman]

[Elaine]
