Brewster's Millions is a comedic novel written by George Barr McCutcheon in 1902, originally under the pseudonym of Richard Greaves.

Brewster is required to spend every penny of his grandfather's million within one year, resulting in no assets or property held from the wealth at the end of that time.

Brewster is required to demonstrate business sense by obtaining good value for the money he spends, limiting his donations to charity, his losses to gambling, and the value of his tips to waiters and cab drivers.

Brewster's challenge is compounded by the fact that his attempts to lose money through stock speculation and roulette prove to increase his funds rather than decrease them.

Brewster's would-be wife Barbara Drew turns down his marriage proposal early in the year, believing him to be financially irresponsible and bound to a life of poverty, and his attempts to win her back repeatedly fail as his attention is entirely absorbed by the requirement to spend so much money.

At the conclusion of the year, he succeeds in spending the last of his funds, which he has meticulously documented, and confesses his love to another woman, Peggy Gray, who has been sympathetic to his lifestyle despite knowing nothing about his challenge.

Shortly after the wedding, the executor of his uncle's will arrives to inform him that he has successfully met the challenge and that he has come to deliver the money to Brewster in person.
