Da Drums, Da Drums

In The Blue Dahlia, (1946) Alan Ladd plays a navy pilot newly returned from the war.  After arriving stateside, he discovers that his wife is having an affair with a nightclub owner played by Howard DeSilva.  After Ladd's wife is murdered, he becomes the prime suspect.  With the help of Veronica Lake, he searches for the true killer.  It turns out it's not the club owner.  His best friend from the war, played by William Bendix,  suffers from PTSD.  Every time he hears jazz it triggers memories of being shot down in the south Pacific and his survival on an island, inhabited by a local tribe.  "Da drums, da drums," he shouts, and then he loses self control and kills Ladd's wife.  The Blue Dahlia was written by Raymond Chandler.  Still, I prefer This Gun For Hire, in my opinion, Alan Ladd's best movie.
