Deadly Ruse. Deadly Series, #14

As the war's outcome shifts, deception is an art--and survival depends on who's painting the picture. When British spy Olivia Redmond is summoned again by her elusive spymaster, she's expecting danger--not an invitation to teach drawing to captured German generals at Trent Park House. But beneath the genteel cover of sketches and civility lies a deadly ruse: the lavish POW mansion is wired for sound, every whispered secret a weapon in Britain's intelligence war. Among the prisoners is Oberst Bernhard, a conflicted German officer from Livvy's past.
When murder, stolen jewels, and a suspected plot among the prisoners ignite within Trent Park, Livvy must decide whom she can trust--and how far she'll go to expose a truth wrapped in loyalty and lies. From the candlelit salons of wartime espionage to the shadows of betrayal, Deadly Ruse is a gripping historical mystery where every stroke of trust could be fatal.
