A Passing Opportunity (S06E01)

Frank Jesmond is on hard times and in danger of losing his family when a man named Laughlin gives him a job as a hitman, the mark being Peter Madison, a school contemporary of Frank who has done very well for himself in the States and is back on a visit. Frank arrives at Peter's hotel and introduces himself, and, for old times sake, the two men go to Peter's room for a drink. (Prime Video)
