When a young bride moves into a country manor, long repressed childhood memories of witnessing a murder come to the surface.

During her many visits to friends and relatives in other villages, Miss Marple often stumbles upon mysterious murders which she helps solve.

Stu Bailey and Jeff Spencer are the wisecracking, womanizing private-detective heroes of this Warner Brothers drama. They work out of an office located at 77 Sunset Strip in Los Angeles, California, right next door to a snazzy restaurant where Kookie works as a valet.

Hale also join the firm, and Suzanne is their leggy secretary.
