The Elysium Gambit

Retired Greek detective Inspector Nadia Stavropoulos boards the ultra-luxury MS Elysium on a quiet assignment: keep discreet watch on a growing gambling problem among the ship's wealthy passengers. What she finds instead is Victor Lang — a British card mechanic of extraordinary precision who has been operating undetected across Europe's most exclusive venues for fifteen years. When American tech billionaire Harlan Voss is found dead in his locked Presidential Suite the morning after a high-stakes poker game, with no sign of forced entry and every door bolted from the inside, Nadia knows this is no natural cardiac event. As the Elysium sails through the glittering Greek islands — Mykonos, Santorini, Rhodes, Crete — she pieces together a conspiracy of marked cards, a rare untraceable poison, and a locked-room mechanism of cold elegance. Someone has done this before. And fifteen years ago, in Athens, Nadia came close enough to know it. With the help of an Italian art dealer who notices things for a living, a Ukrainian investigator who has been hunting Lang for three years, a ship's illusionist who knows more than he should, and two elderly sisters who have been watching from their deck chairs since 1987, Nadia must expose the killer before the ship reaches its final port — and before she becomes the next name in a very private ledger. Atmospheric, precise, and quietly devastating — a classic locked-room mystery set on a floating palace in the Mediterranean sun.
