Bah Humbug case when Dr Pangloss appears to be not murdered at all - as can be seen by this picture of him relaxing on a park bench.
Said Inspector Lestrade "This is not an uncommon event. I myself have on several occasions declared that a person had died when in fact they were just asleep. Apparently Dr Pangloss had closed his eyes for a moment as he attempted to work out why the insurance companies refusal to pay JP's bills was evidence of this being the best of all possible worlds".
As a result Professor Plum has been released by the police and later made the following statement: "I was in a bit of a stew thinking I'd been deserted but didn't crumble and am now leaving unbruised by the encounter."
A bit of Christmas cheer for all in which even the bah humbugs were seen to manage a smile.
