Your team will meet the Chief of Police in a secret location in the 20th century East End to get you up to speed on the investigation. Then you'll take to the streets to find witnesses, gather clues and interrogate suspects. By the time you've solved the murder, you won't even have realised you've clocked up 13.1 miles.
