"Vincent starts to wonder about the role of Walter's attractive secretary, who called for the good samaritan and whether anyone will actually drink the lethal potion. There's also a running joke about what's happening to the poor pot plant.
"It's a highly original comedy thriller, full of mistaken identities, hilarious consequences and some great laughs. The challenge is keeping the drama realistic while the humorous undertones help to lighten the sinister plot."
"I chose Natural Causes for my next show because I'd always wanted to direct a black comedy," she said. "I also greatly admire playwright Eric Chappell, who has had many successes in the UK with television sitcoms, such as Rising Damp, and plays in the West End."
"The character is nervous to begin with and quite unsure if he really wants to go through with it. But Walter is encouraged by his secretary, so his emotional state varies throughout the play, which has been a challenge to get right."
"Natural Causes appealed because I felt it was challenging and it gave me the chance to work with director Susan Vincent once more," Les said.
