My Laugh Comes Last by James Hadley Chase
Farrell Brannigan, President of the National Californian Bank, is an extremely successful man. So when he builds another bank in an up-and-coming town on the Pacific coast, he is given worldwide publicity, and this new bank is hailed as 'the safest bank in the world'. But Brannigan's success came at a price and he made many enemies on his way up the ladder. It seems that one of them is now set on revenge and determined to destroy both the bank and Brannigan himself.
