Bright Orange for the Shroud (1965) is a sixth novel in the Travis McGee series by John D. MacDonald.
The plot follows McGee as he attempts to salvage the money of friend Arthur Wilkinson after the man is defrauded in a semi-legal confidence scheme involving a land deal.
After spending several weeks nursing Arthur back to health, McGee scouts out the lower-level conspirators and forms a guarded friendship with Vivian Crane, whose husband's law practice has been ruined by rumors of his participation in the scam.
McGee goes into the house and finds Vivian has committed suicide with a pistol after killing her husband, who lay in a drunken stupor during her rape.
McGee alters the crime scene to create the impression that Waxwell killed both Vivian and her husband, then phones in an anonymous report to the police.
