" The Metropolitan Police has a very straightforward approach to murder investigations, not for them the detective’s gut instinct or the intricate logical deductions of the sleuth savant. No, what the Met likes to do is throw a shitload of manpower at the problem and run down every single lead until it is exhausted, the murderer is caught or the senior investigating officer dies of old age.
