Dying onstage happens all the time, but it's the literal fate of egotistical, womanizing tenor Leo Carrillo as he collapses mid-aria before a stunned Hollywood Bowl audience. LAPD plainclothesman Chester Morris and forensics whiz Madge Evans have to sift through a copious suspect pool before the killer takes a curtain call. Frank McHugh, Benita Hume, Grant Mitchell, and Carrillo's future "Cisco Kid" compadre Duncan Renaldo co-star. 66 min. Standard; Soundtrack: English Dolby Digital mono.
