A murder and a missing body interrupt a getaway in the south of France . . .

Waldo and Averil Keelagher were looking forward to a holiday in the south of France in their new caravan.

Panicking, Waldo and Averil pack the body into the back of their car and rush to the nearest police station in Cannes. But things really take a turn for the peculiar when, after reporting the crime, the couple heads back to the car to find it has been stolen—with George's body still inside.

Now, Superintendent Littlejohn, who happens to be on holiday nearby, finds himself caught up in one of his most complicated and unorthodox cases yet . . .
