In the fifth book of the Sam Dawson Mystery Series – YESTERDAY CALLING, a dangerously unpredictable psychopath bent on revenge victimizes Sam Dawson and his daughter for choices Sam made decades earlier in this edge-of-your-seat thriller. The past and present collide as author Horn adds another riveting chapter to his award-winning Sam Dawson Mystery Series. But nothing is as it seems in YESTERDAY CALLING.

“This one is a beguiling 5-Star read from Wyoming’s master of suspense. Highly, highly recommended!,” wrote W. Michael Gear and Kathleen O’Neal Gear, New York Times bestselling Wyoming authors of Lighting Shell, in their review of the book.

As with many of the Sam Dawson Mysteries, the setting is southeast Wyoming. YESTERDAY CALLING incorporates Cheyenne and Laramie, as well as Berthoud and Boulder along Colorado’s front range.

The Sam Dawson Mystery Series features Wyoming-based photographer Sam Dawson whose unnerving knack for stumbling upon trouble leads him to uncover dark secrets, lost graves, espionage and even mass murder. With his trusty hound at his side, Sam must reluctantly abandon his favorite Wyoming fishing haunts to unravel the truth to keep himself, friends and family out of harm’s way.
