The Keys of Hell (Paul Chavasse Series #3)

Super spy Paul Chavasse is looking forward to a vacation when the Chief says there's a simple little job he'd like Chavasse to do first. Of course nothing the Chief ever wants is simple or little: it is invariably large and lethal. The job: get into Albania and put a dangerous double agent out of commission--permanently. What Chavasse doesn't know is that someone has set a trap for him--someone who has planned his destruction--someone who holds the keys to hell!\
