The second instalment in the Crime Doctor series, in this one he gets involved in a murder case involving poison.
A retired businessman dies due to poisoning, the man's secretary Jimmy (Lloyd Bridges) fears he will be accused of the crime as he has a reputation for experimenting with poisons, having being accused of poisoning someone before. He enlists the help of criminal psychiatrist Dr Ordway (Warner Baxter) who uses his analytical skills to unravel a complicated plot which is linked to the disappearance of the victim's business associate years ago and embezzlement.
An early example of criminal psychology being shown on screen. This makes what is otherwise a good but fairly standard crime B-movie a bit different and very watchable. Good performances, especially from the smooth Baxter add to the joy.
