UK Travel Industry Entrepreneur’s Latest Crime Thriller

“This book grabs you by the throat and doesn’t let go. So many twists and turns, it keeps you glued till the end. An absolute ‘must read’ for any lover of crime thriller stories.”
– Joe Mainous, Director (retired), University of Kentucky English Department

Former soldier Frankie Armstrong is at a low ebb; his wife has left him for a work colleague. Then Frankie gets an unexpected call from Joe, the American soldier who saved his life in the Gulf War. It’s years later, but now Joe is asking him to repay the debt. Frankie decides he has nothing to lose, and grabs the opportunity to flee from a cold wet Manchester to sunny Florida.

His task is to find Joe’s nephew who’s gone missing while diving for treasure. Frankie soon discovers he’s not the only one investigating the disappearance, but the others are playing by a very different set of rules... Frankie’s investigation takes him into the world of Miami mobsters, molls, maritime murders and a secret survivalist’s camp deep in the heart of the Everglades. Bodies are stacking up, and time is running out for the missing men.

As a child, Costello was confined at home after an operation. It was during this time that he developed his passion for literature, reading everything he could lay his hands on. It was the power of words that fascinated the young Costello and naturally led him to writing in later life. And after retiring from a successful career in the UK travel industry, he was able to make writing his full-time focus. Five books later and his latest novel is a gripping thriller set in Florida, a place Costello knows well:
“Many of the ‘everyday people’ I meet in Florida are anything but. All seem larger than life, and many become the basis of characters in my books. Naples Florida, situated on the Gulf of Mexico and just a few miles from the subtropical wilderness of the Everglades, provides a rich seam of material for my books,” comments Costello.

The author’s succinct and punchy style adds great pace to the plot and makes You Owe Me a gripping read from the very outset.
“Costello’s latest offering is a compelling, rip-roaring read. Fast-paced throughout, with fiendishly clever twists and turns. One thing this author doesn’t do – is dull!”
– ex-detective, Roger Bescoby MABI MWAD
