Tabs Productions (The Mysterious Mr Love, Who Killed "Agatha" Christie?) return to The Haymarket with Richard Harris' (Stepping Out, Outside Edge, The Avengers, A Touch of Frost) psychological thriller.

The time: 1981

The cast: The detective, the playwright, and the man who's brought them together.

Humourless and drab Stone invites Dee, a television playwright, over to his flat to discuss a script. However, to her surprise, the man with whom she is having an affair with turns up for an entirely different reason.

But nothing is as it seems and as the plot twists and turns, the motive of their host gradually becomes clear. They are all, it would seem, in the same business… The Business of Murder.
