So I am now reading (well, finished reading) a book by Michael Crichton called "The Great Train Robbery." In this book, a well-known criminal named Edward Peirce is trying to rob a bank by stealing its money when it makes a voyage on a train. To do this, he must first find four keys. Two are in a bank, one is in the cellar of the bank owner, and another is around the neck of a trusted bank employee. To steal the keys that are in the bank, his man must go up some stairs, through a door, unlock a cabinet, make an impression of a key, and get out and back to his hiding spot. In under 64 seconds. Before the guard comes back from the restrooms. Once he gets the keys, and once he gets on the train, he must get into the guarded baggage car (having bribed the guard before), open both safes with the four keys (each safe has two locks), throw the money to the waiting man on the side of the railroad, put the fake bags filled with lead in the safe, and get back to his compartment by climbing over the roofs of the railcars. How he will do this, no one knows. But they will still try.
