You Owe Me: Murder Mystery with a terrific twist at the end (Frankie Armstrong Book 1)

He saved Frankie’s life. Now Frankie owes him everything — including, possibly, his own life...
Frankie Armstrong has hit rock bottom. His wife has left him. His future looks bleak. Then an unexpected phone call from Joe — the American soldier who dragged Frankie out of the line of fire in Iraq — pulls him back from the edge. The favour seems simple enough: fly to Florida, find Joe’s missing nephew, come home. But nothing in Florida is ever simple.
Within hours of landing on the sun-drenched Gulf Coast, a missing person case spirals into something far darker. Mafia thugs. Sunken treasure. Murder. And a million-dollar secret that Joe forgot to mention. With only a stray dog for backup, Frankie races to stay one step ahead — of the police, a ruthless PI, and killers who don’t take prisoners. But the closer he gets to the truth, the more he wonders: was he sent here to save someone, or to be silenced?

You Owe Me is a pulse-pounding crime thriller packed with sharp wit, sun-soaked atmosphere, and twists that will leave you breathless.
