Two Much

In Two Much, Donald Westlake takes what should be a ridiculous and far-fetched plot — the protagonist Art Dodge, a greeting card designer, pretends to be both himself and a fictitious twin brother Bart so that Art/Bart can sleep with a pair of identical twins — and turns it into one of his best books, full of real suspense and dark humor. If you liked Westlake's masterpiece The Ax (1997), this is a good book to read next.
