A police officer is shot in the middle of Central Park from a building way outside the park. He dies right away. Sadly, the bullet, an important piece of evidence, is buried into the officer's horse, Blue. Removing might end Blue's life.

A young John Doe, nicknamed 'Slick', is found lying across the rails of an underground subway. At first, he appears to have died from third-rail electrocution, but an autopsy suggests that he may have met his end by other means of electrocution. Meanwhile, Leo Whitefield is found shot dead at close range in a gallery he owns, with no sign of break in or theft, and a construction worker turns up with a fatal injury to the head.
