Castle in the Air — Donald E. Westlake

The Italian Job meets Ocean's Eleven in “the kookiest  . . . craziest” crime caper ever written by crime fiction Grandmaster Donald Westlake (New York Times).

Four teams of international thieves race through Paris to steal a king's ransom from the walls of a disassembled castle.

When four groups of international heist artists team up to pull off the theft of the century -- stealing an entire castle, and the treasure hidden in its walls -- what could possibly go wrong?
 
Well, consider this: none of the master thieves speak each other's languages . . . and no one knows precisely where the loot is stashed . . . and every one of them wants to steal it all for him or herself.
 
It's Mystery Writers of America Grand Master Donald E. Westlake at his wildest, a breathless slapstick chase through the streets of Paris only one step ahead of the law -- and each other.
