Plot hole: The big locked room mystery is such only because the detectives build it up as one; they don't make any remark about the fact that the door can be locked from inside without the need of a key, they don't check the door frame or the lock (which would have revealed that it was bashed open while unlocked) and they do not even consider for a moment the idea that someone could have made a copy of the keys, which is the first thing anyone would have assumed. Not just that; nobody on the floor who has been working at the bank for years says anything about some cleaning lady they haven't ever seen before and that happens to be the first respondant to the murder.

DI Jack Mooney: My grandfather told me a story once, about these two wolves fighting inside all of us. And one of them is anger, envy, self-pity, regret. The other one is love, truth, faith, hope, that sort of thing.
And I asked him "which one of the wolves would win?" And do you know what he said?
"The one you feed." (00:18:15)
Question: Why did the cord on the wall phone in the police station change from straight in the early episodes to coiled later?
