Have Mercy on Us — Philip Luber

THE END OF INNOCENCE . . .

1n 1845, Thoreau found the meaning of life at Walden Pond. Now police are searching for the meaning of death there--the grisly work of a cunning serial killer with a unique calling card. To psychiatrist Harry Klein, the chilling case hits too close to home: The murder suspect is his live-in lover's ex-boyfriend, a man embroiled in a heated battle over developing Walden Pond.

Klein is drawn into the center of the horrific case--in a search for a killer that turns into a harrowing struggle between evil and an innocent place, between a serial killer who calls himself the True Believer and Klein, who has everything to live for and maybe nothing left to lose. . . .
