“With burglaries, you’d use maps with coloured pins, because they’ll help you to spot patterns such as different times or places,” he says. “You might spot burglaries that happened next door to each other, when [at first] it wasn’t clear from the addresses that the two places were even close. With other crimes, you might map out who a villain’s mates are. You might find out who their friends were when they had been in prison, and see who they were linked to. With a kiddy murder, you’ll do a full chart of the family with all the connections showing, and profile them all. You might find that an uncle is connected to a villain, or something like that.”
