London Falling (Shadow Police, 1) [Cornell, Paul]

Police officers Quill, Costain, Sefton, and Ross know the worst of London--or they think they do. While investigating a mobster's mysterious death, they come into contact with a strange artifact and accidentally develop the Sight. Suddenly they can see the true evil haunting London's streets.

‚  

Armed with police instincts and procedures, the four officers take on the otherworldly creatures secretly prowling London. Football lore and the tragic history of a Tudor queen become entwined in their pursuit of an age-old witch with a penchant for child sacrifice. But when London's monsters become aware of their meddling, the officers must decide what they are willing to sacrifice to clean up their city.
