[set 1, Vol. 2], Sleeping Murder ; 4:50 From Paddington
 When Giles and Gwenda Reed move into their dream house in a seaside resort, Gwenda finds herself haunted by the vision of a body in the hall. It takes Miss Marple's keen intuition to enlighten the Reeds: the imagined body is Gwneda's stepmother, thught to have run away long ago--but was in fact strangled when Gwenda herself lived in the house as a young child.  On a jaunt to visit her friend Miss Marple, Elspeth McGillicuddy chances to glimpse a man strangling a woman on a passing train.
