[fluff]

From the offficial site:

A devoted father and seasoned detective who’s seen most of what the city of Seattle can throw at a person. Yet he’s never come across the likes of John Doe. Reluctant at first to accept his help, Hayes begrudgingly grows to trust Doe’s bizarre outbursts of facts and theories. They form a tentative bond, but Hayes never forgets there must be more to the mysterious Doe than he’s sharing.
