Hard-boiled versus cozy mysteries

Jay Catherman:

In a cozy mystery novel, you have an amateur sleuth standing over a neatly laid out corpse, with a cat sleeping on the mantel, and water on the boil for tea.

In a hard-boiled mystery novel, the detective is some sort of professional sleuth, the mutilated corpse is hanging from the fireplace and the cat is boiling in the kettle.
