Robert Montgomery as Philip Marlowe on a special one-hour Sam Spade episode entitled "The Khandi Tooth Caper." The episode was originally run on Suspense (both shows had the same producer, William Spier), during the period when Montogmery was the host. Later, it was run as a two-parter on the regular Spade series. Montgomery had, of course, played Marlowe in the film version of The Lady in the Lake.  In this Suspense/Sam Spade episode, Sam calls Marlowe on the phone and they discuss a case.
