Mardler and the Fleeing Man

You put your head down and sprint across the road. You can hear the carriage to your right, skidding through loose dirt as it tries to stop. Mardler is running beside you and you close on the fleeing man. He looks back and sees you and then he trips on a piece of rubbish. The suspect has been stealing drugs from hospitals all around London. So the guy's a drug addict and a thief. Hmm, I want to see Yates. And so actually the distance I'm going to carry over time or something is probably shorter. That is not the first time maths has been actually useful in my life. Okay, investigation score. Plus one.
