Kersley But he walked in through the front door. I don’t think so, Mr Sherwood.
Sherwood Then she must have been surprised by an intruder.
Kersley Rather familiar words for an intruder I would have thought. But singularly appropriate for a husband who had returned unexpectedly and not via the front door. ‘How did you get in?’
Sherwood But I didn’t return unexpectedly via any door.
Kersley Then via the fire escape, perhaps?
Sherwood Or the fire escape.
Kersley Then how about the kitchen window?
Sherwood Or the kitchen window.
Kersley Then who slipped back into the kitchen just before Mr Webster came in?
Sherwood It could have been the wind that caused the door to slam.
Kersley Then how do you explain the shouting, the quarrelling and the turning over of furniture?
Sherwood I accept Mr Webster’s explanation - that there had been another burglary.
Kersley So how did this burglar enter the building, when there was no sign of a break-in?
Sherwood Via the fire escape and the kitchen window.
Kersley But the window had bee
n opened from the inside?
Sherwood My wife often opened it on a warm evening.
Kersley In March? Ah, I see, so it was your wife who let the burglar in?
Sherwood That’s a ridiculous suggestion, Mr Kersley, and you know it.
Kersley As ridiculous as suggesting that it was a burglar who caused the bruising on her arm.
Sherwood Not at all. The bruising could have been caused by a struggle with the burglar.
Kersley Rather than a struggle with you?
Sherwood Why should she be struggling with me?
Kersley Because when you returned to inject her, you were horrified to discover she hadn’t drunk the glass of wine that contained the sedative you had prepared for her.
Sherwood Then how do you explain the unopened ampoule left in my bag?
Kersley Because you left it there, Mr Sherwood, having only managed to inject five of the ampoules before you were interrupted by Mr Webster, when you fled to the kitchen, dropping the rubber glove on the floor.
Sherwood Have you forgotten that the glove belonged to my wife?
Kersley Have you forgotten that it was soaked in Potassium Chloride?
Sherwood From a bottle of grapefruit juice - as Professor Forsyth confirmed.
Kersley From an injection, that induced a heart attack, as Professor Forsyth demonstrated.
