Once a Crooked Man - David McCallum
Harry Murphy , New York-based actor, had just finished yet another audition – spoiler alert: he wouldn’t win the part – and badly needed to pee. So he slipped into the Chinese restaurant he was passing, hoping to empty an overflowing bladder. The four men at the table chased him off, so a desperate Harry ducked into the neighboring alley and watered the brick wall instead. What he overheard standing under an open window was (somehow) sufficient to send the young man across the pond to London, planning to warn a complete stranger (for whom he had only a surname) that someone in America planned to terminate their arrangement, whatever it was – permanently.
