Description
INTERNATIONAL DETECTIVES: THE COMPLETE COLLECTION (Books 1–6)
Six cities. Six cases nobody wanted solved. One detective duo who don’t know when to walk away.
Over 3,400 reader reviews across the series.
Private investigators Leo Keane and Allissa Stockwell take the jobs nobody else will touch — the ones that begin with a missing person and end somewhere far darker, in cities where they don’t speak the language and can’t trust the police. From the incense-thick backstreets of Kathmandu to the Byzantine maze of Istanbul, every case pulls them further from home and closer to something that would rather stay buried.
All six novels are collected here for the first time.
Book 1 — Kathmandu Killers. A routine missing persons case in Nepal becomes a deadly game of cat and mouse through the alleys of the old city.
Book 2 — Hong Kong Gone. A city built on money and silence, and a corruption case that reaches higher than anyone will admit.
Book 3 — Berlin Underground. Cold War secrets buried beneath the streets, and someone still willing to kill to keep them there.
Book 4 — New York Nightfall. A serial killer working the city’s blind spots, and a hunt that runs out of time before it runs out of bodies.
Book 5 — Riga Rising. A decades-old disappearance in the Baltic, and a truth that has waited a very long time to surface.
Book 6 — Istanbul Icarus. Where East meets West, Leo and Allissa race to stop a catastrophe with a global reach.
I’ve walked every one of these cities myself — sat in the cafés, ridden the trains, got thoroughly lost in the backstreets — and I’ve done my best to put you right there on the page alongside Leo and Allissa.
