Thriller (S2 Ep 6 - K Is For Killing) (1974)

S2, Ep 6: K is for Killing. After an assassin's bullet fails to kill tycoon David Garrick, eccentric husband-and-wife detective team Arden and Suzy Buckley are hired to protect the millionaire. The pair have to discover the identity of the would-be-killer before her or his next attempt at murder succeeds... Starring Gayle Hunnicutt, Stephen Rea, Jean Kent, Christopher Casanove, Peter Dyneley, Derek Francis, Frances Bennett, Shirley Cain, Oliver Smith, Arthur White, James Appleby, Sally Miles, Francis Mortimer, Julia Breck and Gilly Flower. Containing an early star role for Stephen Rea (who, surprisingly first found fame in soap Crossroads from 1967-68 as Pepe Costa), this mystery edition of Thriller seems to divide fans. Some utterly detest it as flippant and farcical, others enjoy it's carefree approach to crime solving by couple Suzy and Arden Buckley (Rea and Gayle Hunnicutt). Whatever your feelings towards it, just approach it as a mild diversion to enjoy from the problems of the world and you should get on fine. Enjoy.
