Anthony Cade was only trying to do a friend favor. It was just his luck that this favor landed him smack dab in the middle of a dangerous murder investigation. First he has to try to prove he's not the murderer and then while the French S ret and Scotland Yard investigate he has to make sense of two murders, a jewelry heist, and heirs to a lost throne all before the murderer can bring their plan to fruition and make their get away.
A fabulous, fast paced adventure. One of Christie's best.
