In fact, they even apparently convince a highly suspicious Detective Sergeant

The nightmare situation becomes more and more complicated, including the sudden appearance of a murdered man until, with the arrival of Chief Inspector Gale, a series of ingenious twists brings an eventful evening, for all concerned, to a surprising close
