Heat Wave

American writer Mark (Alex Nicol), narrating, is done working, spying Carol (Hillary Brooke), across from his rental on an English lake, recalls the party where she wounded husband (Sidney James) and stepdaughter (Susan Stephen), steam ensuing, in the Hammer Films Noir Heat Wave, 1954.

American writer Mark (Alex Nicol) the morning after the party on England’s Lake Windermere, where he met host Beverley (Sidney James), meets his daughter (Susan Stephen), but the subject is the wife, her stepmother, Carol (Hillary Brooke) whom we know, via flashback, winds up dead, in the Brit-Noir Heat Wave 1954.

Presumably Ken Hughes, the novelist, screenwriter and director, means “slow” not “sloe,” regardless, his opening introduces Alex Nicol as American hack Mark, and places the story at a real location, England’s largest natural lake, in the Hammer Films Brit-Noir Heat Wave, 1954, co-starring Hillary Brooke.
