Beech and Conway attend a police event to receive medals for long-standing service and excellent conduct. Beech is surprised to find that an old flame of his has defected to C.I.B., and is currently investigating one of the officers with whom he trained at Hendon. Anxious to get to the bottom of the investigation, Beech questions his old friend on details of his misgivings. Stamp's day to face the police disciplinary board has arrived, but after seeing one of his old friends from Stafford Row being sacked for a minor driving offence, he does a runner. Garfield has to convince him to face the board to clear his conscience once and for all.
