The Murder of Dr. Harrigan

Hospital administrator Robert Strange, who is claiming all the credit for a new anesthesia developed by several doctors, has an operation performed by John Eldredge. Strange disappears and Eldredge is murdered. Police detective Joseph Crehan shows up to solve the mystery, but it's Doctor Ricardo Cortez and nurse Kay Linaker who do the work.

It's one of a dozen 'Clue Club' mysteries from Warner Brothers in the mid-1930s, and given it's from a novel by Mignon Eberhart, it's a decent enough mystery, if a trifle rushed at 67 minutes. The cast includes Mary Astor -- supposedly she turned down Miss Linaker's role and was made to play a lesser one as punishment, which makes no sense to me -- Mary Treen, Bill Elliott, and Don Barclay and Johnny Arthur as comic-relief patients. It's a trifle generic, but good.
