S4·E2 Devils on Horseback (2)

Liz claims the money is winnings from a bet and Henry releases her but notes that Jerry too has a healthy bank balance and surmises he was trading inside information for cash. Tony apologizes to Henry but tries to push Bob into accepting the take-over and Henry's mystery man proves to be a private eye, since Tony has been fixing races and the Jockey Club have hired him to get proof. Henry believes Tony got Jerry to nobble his horses and killed Ben when he found out. He has the correct motive but the wrong suspect and it's Margaret who literally stumbles on the real killer and has a close call with them. Meanwhile Nicola is annoyed when a spoilt school-friend appears to be making a play for Gary, though she is actually trying to poach him for her restaurant - unsuccessfully.
