Gordon Carson (Stephen Crane) has had two wives die of accidents during the honeymoon. His third wife (Hillary Brooke) calls in the "crime doctor," Robert Ordway (Warner Baxter), to find out if her hubby is mad or a murderer. But Ordway instead finds himself investigating Carson's own murder in a locked room. There's also a famous writer (Jerome Cowan), and a brother and sister team of Spanish dancers who are rumored to be vampires. The Crime Doctor's Courage tries to drag in all sorts of stuff to make it interesting, but while it holds the attention it never quite develops into anything that great. Baxter has a lot of charm as Ordway, however.
Verdict: Okay B mystery. **.
