Slick work for dependable Asst. D.A. Gibson, as once again he untangles a too simple case of suicide-cum-accidental death, and proves his case against a glamour girl who wanted her man. Music student background -- a pregnant girl dead -- a stone deaf land-lady whose dreams about being an heiress turned out to be true- and a thorny set of suspects whose moral code may give the squeamish pause -- add up to a plausible runaround of New York's Bohemian life.
