" Murder investigations start with the victim, because usually in the first instance that's all you've got. The study of the victim is called victimology because everything sounds better with an 'ology' tacked on the end.

Next time you watch a real murder investigation on the TV, and you see a group of serious-looking detectives standing around talking, remember that what they're actually doing is trying to work out what sodding order the mnemonic is supposed to go in. Once they've sorted that out, the exhausted officers will retire to the nearest watering hole for a drink and a bit of a breather. "
