The Dutch Blue Error

To solve a murder, Brady must find a copy of the world€s rarest stamp. It is a small paper square with uneven edges, dark blue in color, and bearing a smudged portrait of a long-dead king. It doesn€t look like much to Brady Coyne, but the stamp known as the Dutch Blue Error is one of a kind - a philatelic freak worth at least one million dollars. It is the prize possession of Ollie Weston, a wheelchair-bound Boston banker, and it is valuable enough that for its sake, several good men will die.

A fellow collector contacts Weston, claiming to have found a second copy of the Error - a claim that, if truthful, would destroy the stamp€s value. Weston sends his attorney, kindhearted Boston lawyer Brady Coyne, to purchase the rogue stamp for two hundred fifty thousand dollars, but just before the hand-off, the collector is killed and the stamp disappears.

Find the stamp and Brady will find the killer - but that will involve risking another one-of-a-kind item: his life.
