Just Before Dawn

This time Dr. Ordway (WARNER BAXTER) is involved in a plot concerning diabetics and insulin with the reliable MARTIN KOSLECK as the villain of the piece who is not above switching a bottle of insulin for poison and making Dr. Ordway the unsuspecting killer.

While there are plenty of suspects who might have wanted the deceased man out of the way, the plot hinges mostly on sinister doings at the Ganss Mortuary run by Kosleck who is prone to dispose of anyone who is going to reveal information to Dr. Ordway.

It's a good old-fashioned mystery with some creepy characters among the villains assisting Kosleck and the plot is less murky than some of the others in the crime doctor series. There's a clever plot twist with the doctor using supposed blindness as deception in catching the killer.

Summing up: One of the better entries in the crime doctor series.
