Plot hole: Dan, the policeman, finds a love letter written by Ben to Daisy, Dan's sister. The letter says "Meet me in the summer house tonight." When the girls arrived 2 to 3 days ago, Ben and his brother were arguing about the letter, which was written on blue paper. When Daisy is killed, Dan, ridiculously, accuses Ben - only on the blue letter as evidence, which we know was written days ago, and Daisy was killed in the afternoon, not at night as the letter says; plus, Dan says Daisy was struck with a heating tube, just like the ones where Ben works on the winery, but anyone could have picked it up. The evidence is stupid, but Ben is arrested, placed in handcuffs and taken away.
Plot hole: When Daisy is killed, Dan comes around to collect her things. So we'll be able to see him reading one of Daisy's love letters from Ben and accuse Ben of Daisy's murder, when Dan takes the box from Stuart, who is holding it with his hands underneath, keeping everything in, he holds the box with his hands on the side, deliberately, so the love letters fall out to the ground - and how convenient that nothing else falls out, just the love letters. But the letters were written before the girls arrived - they saw them - so how could Dan accuse Ben when the blue one has Ben asking Daisy to meet him in the summer house, but it was days ago, not relevant now.
Plot hole: When Laura, alone in the girls' room, hears the noises in the attic, she runs to get Rosemary. Problem is: Horace is the one who makes the noises and when Laura finds Rosemary, Horace is in the bar - not downstairs, making noises as he should be.
Plot hole: In the garden, when Rosemary and Laura haven't done much clearing away yet, a girl loses her mobile in the garden. Instead of spending "hours" searching for it, why don't they just ring it? Or explain that the battery is dead and they can't ring it?
Plot hole: The girls refer to Holly's owner as Mr Volker, even though they now know her owner is Mr Allbright. For plot reasons, they have to say to Sherry that Mr Volker is Holly's owner, because now she knows she's killed the wrong man, and she'll have to kill again.
Plot hole: The first man to be killed is a psychiatrist - "a very private man". So, if he was "very private", how did the "hip man" know if he did or did not have any psychotic patients who would want to kill him? He wouldn't.
Chosen answer: Maybe she thinks she's so old that she'll be back in the mortuary soon, so why go home?
