The Case of the Borrowed Brunette

When Perry Mason stumbles upon a classified ad for a brown-haired woman with specific physical attributes, he takes note of the seemingly suspicious request. Then the woman hired for the job reaches out, fearing that her new employer--who pays her and her chaperone to stay inside an apartment and answer to another woman's name--might be using her for nefarious purposes. But by the time Mason works out the first mystery, a second, with murder, is just getting started, and that's only the first twist that awaits him as he endeavors to prove the innovence of "the borrowed brunette." -- book jacket
