Continuity mistake: When Rosemary visits Hamilton Teed, he shows her a picture of Martin and Jim, aged 10, then puts the photo down on the desk, but a second later, the photo is gone.
Continuity mistake: When the girls are just finishing their look of the walled garden, Laura's scarf that has been visible on both sides up until now vanishes on the left side, then it comes and goes repeatedly.
Factual error: When Rosemary finds Mr Teed's dead body, the kettle is boiling. It's the type that will keep boiling until someone turns off the stove or takes it off the heat; neither of these things happen, and yet, before the scene is finished, the kettle stops making that boiling sound.
Plot hole: When Eddie finds the hammer that killed Cousin Jim, Rosemary and Laura are on his tail, so he rushes to the river, and so does Martin and the constable. Problem is: Eddie and the girls are on one side of the river and Martin and the constable are on the other side of a river that is impossible to cross where they are - there are bridges, but not there. So, if Martin and the constable were heading for the hammer, why did they go to the wrong side of the river? It's all very dramatic, as Eddie has to dive into the water, but it's ridiculous, plot-wise.
Continuity mistake: About halfway through, when the girls are sitting at the dining-room table and Martin walks in with a decanter of red wine, he proceeds to fill the girl's glasses, but not his own, and yet, in the next shot, his glass is filled.
Other mistake: When the girls are driving to their new job, the instructions were "turn left when you see the post box". But they turn left and then see the post box.
Audio problem: Near the end, Suzanne puts the dishwasher on, which is in the kitchen, near the long kitchen table they are all sitting around. At first, we can hear the dishwasher, not very loudly but it's there, but when they expose Suzanne as the killer, the dishwasher is all but silent even though its been running for at most 10 minutes, so it should still be noisy.
Continuity mistake: In the beginning, the Land Rover has something on the roof, like a ladder, but not long afterwards there's nothing on the roof.
Continuity mistake: When Laura finds the hammer with blood and hair on it, Rosemary finds the constable and tells him where the hammer is. When we first see the constable's car, it's in a ditch. But when he gets into it and drives away, it's no longer in the ditch, but beside the road.
Chosen answer: Maybe she thinks she's so old that she'll be back in the mortuary soon, so why go home?
