is a 1965 British horror thriller film directed by Silvio Narizzano, and starring Tallulah Bankhead, Stefanie Powers, Peter Vaughan, Yootha Joyce, Maurice Kaufmann and Donald Sutherland.

Released in theaters on 21 March 1965 in United Kingdom, it was filmed at Elstree Studios and on location in Letchmore Heath, Hertfordshire, during the summer of 1964.

Before tying the knot, however, Patricia pays a visit to Mrs. Trefoile, the mother of her deceased fiancé Stephen, who died in an automobile accident several years earlier.

Variety wrote that the film "should click with fright fans," praising Narizzano's direction as "imaginative" and the script as having dialogue that was generally "fresher than most pix of its class" while giving Bankhead "numerous chances to display virtuosity, from sweet-tongued menace to maniacal blood-lust.

"[2] The Monthly Film Bulletin wrote: "Though uneven in tone (to put it mildly), this piece of extravagance is at least consistently enjoyable ... One suspects here a laudable determination in Miss Bankhead not to be outdone by Bette Davis' Baby Jane.
