An unimaginably valuable pink diamond has gone missing and a mysterious Russian residing in Switzerland is suspected of having made off with the treasured jewel. But the investigative duo of Johann Friedrich von Allmen and his Guatemalan butler Carlos are on the case. Their search leads from London though Zurich to a grand hotel on the Baltic coast. Amorous adventures and diverting mishaps litter the path through a world of European high culture and luxury, with hard-knuckle forays into global financial markets and high tech moves to manipulate them. This is the second in a series of fast-paced detective novels devoted to a memorable gentleman thief who, with his trusted sidekick, runs an international detective agency to recover stolen precious objects. New Vessel Press will publish the first in the series, Allmen and the Dragonflies, in May 2018.
