Fitzwilly is a 1967 American romantic comedy film directed by Delbert Mann, based on Poyntz Tyler's 1960 novel A Garden of Cucumbers (the title refers to Isaiah 1:8) and adapted for the screen by Isobel Lennart.

Its title refers to the nickname of its protagonist, Claude Fitzwilliam, an unusually intelligent and highly educated mastermind of a butler played by Dick Van Dyke, who commits robberies to maintain the luxurious lifestyle of his employer.

"Fitzwilly" has been leading the household staff on numerous thefts, raids and swindles — including the operation of the fictional charity and thrift shop, St. Dismas — to maintain "Miss Vicki" in the lifestyle to which she is accustomed.

Fitzwilly proposes marriage and agrees to end the criminal operations and tell Miss Vicki everything, but there is a problem: due to Juliet's past interference, the household is $75,000 short of funds, and they have to raise the money by Christmas Day.

Miss Woodworth casually blackmails the assistant district attorney ("the son of my oldest friend") into engineering a suspended sentence on a lesser charge, and blithely offers to write a counter check to the store to cover the amount of the take, money that she does not know she does not have as part of that supposed inheritance.
