Other mistake: The text message used as ploy to cover up the murder was sent at 17:44, but during the flashback showing the killer setting up the murder scene, a wristwatch on the vanity is at about 10 o'clock. (00:44:25)
Other mistake: Meeting with the suspects for the first time, Jack is flipping through the brochure with the player profiles while "The prof" is saying that logistically speaking the murder is impossible. Jack looks down at a page, but the close-up shows a different one. (00:08:35)
The Healer - S7-E4
Other mistake: The coroner report that mentions the nicotine poisoning has also as information in the first column that the victim came from the hospital with a suspected stab wound. That bit of information makes no sense and it's not mentioned in any way. Reused prop? (00:19:00)
Murder on the Day of the Dead - S7-E5
Other mistake: The day of the murder was February 1st 2018, a Thursday, exactly as stated also by the answering machine early in the episode. When Jack checks out (really really late, while any investigator would have easily worked with that data right away, asking them to the provider even, together with the cell phone info) the victim's satnav, it says that her 1 PM trip happened "Sat", a Saturday. (00:04:50 - 00:34:55)
Murder on the Day of the Dead - S7-E5
Other mistake: Something happened to Daisy Anderson, so everyone starts looking for her car. JP says it is locked, but in the close-up of Jack looking inside from the window, you can see the knob of the lock is pulled up. That car is unlocked. (00:06:50)
Other mistake: According to his passport, Michael Bennett was born on July 120th. (00:35:50)
Other mistake: The victim is said to have died between 10 and 11 but the neighbour put his bins out at midnight and heard the fight.
Answer: Most likely they had only tropical exotic drinks, he wanted an old fashioned English beer.
