Perry Mason's keen eye for the ladies gets him an earful of intriguing information from pretty women applying for a very odd job. Seems a mysterious Mr Hines is advertising for a young brunette, and he's very specific about what he wants ... right down to her exact measurements.The looker who lands the gig gets to live in a posh apartment, wear fine clothes and collect a generous salary. Struggling model Eva Martell is thrilled when she gets the job, but her Aunt Adelle doesn't like the scenario one bit, and asks Mason to punch a few holes in Hines's story and see what leaks out. But when someone punches a hole in Hines - with a bullet - the masquerade becomes foul play with a murderer lurking in the wings.
