It Couldn't Have Happened But It Did on AllMovie

Playwright Greg Stone (Reginald Denny) spends most of his spare time at the theater where his latest effort is in rehearsals. Stone's new play is a murder mystery, but the various backstage habitues are every bit as suspicious and sinister as the characters onstage. Sure enough, life imitates art when both of the producers are murdered in a manner strikingly similar to a pair of killings in Stone's play. Naturally, this places our hero under suspicion, forcing him to turn amateur sleuth to track down the real culprit. Evelyn Brent, who like Reginald Denny was a major star in silent pictures, is featured as the victims' feisty secretary, in love with Greg Stone but averse to admitting it.
