Murder mystery play

[Clare A]

A mystery about a mystery, in that I can't remember for the life of me the title of a murder play I saw in London's West End no later than 1991, in which year I moved to the Isle of Man.

A man goes to someone else's flat with the intention of murdering its occupant(s) for some past slight, which I think had put him in prison for a long time.

The tables are turned, however, when they - a couple, I think - trick the would-be murderer into entering the balcony, lock the reinforced glass patio doors behind him and take off on holiday. It is plain at the end of the play that he will die there without food and water or any means of summoning help. Can anyone recall the title and/or author, please?

I saw that play myself just last year.  Its title is:

Murder by Misadventure

Edward Taylor

gen2, I do believe you're right! Thank you so much. Cracking play, wasn't it - where did you see it?

It was an Amateur Dramatic Society production in a village hall just outside Cambridge.  Not sure exactly where or what the group were called as I was visiting my brother at the time.  Not my area of he country, not even my country.  Yes it was a good play and very well done, we all enjoyed it.
