In his family life Angus Stonefield had been gentle and loving, in
business a man of probity, and in his relationship with his twin
brother, Caleb, a virtual saint. Now Angus is missing, and it appears
more than possible that Caleb--a creature long since abandoned to
depravity--has murdered him. Hired to solve the mystery, William Monk
puts himself in Angus's shoes, searching for clues to the missing man's
fate and his vicious brother's whereabouts. Slowly Monk inches toward
the truth--and also, unwittingly, toward the destruction of his good
name and livelihood.
