Every small town has a moment when the real world abruptly intrudes, shattering the town's notions of itself and its people. For citizens of Marshall, Michigan, that moment came August 18, 1967. Nola Puyear was working downtown at the Tasty Cafe that morning when she received a package. She opened it and was instantly killed in a fiery explosion.

But why had someone wanted to kill the well-liked woman, by all accounts a pillar of her close-knit community? For that matter, was Marshall really the quaint paradise it seemed to be?

Secret Witness brings to light startling new evidence and freshly uncovered facts to address these and other questions that, to this day, surround one of Michigan's most brutal murders. Based on extensive interviews with surviving prosecutors, police, and witnesses, Blaine Pardoe re-creates the investigation that pried into Marshall's dark underbelly and uncovered the seamy private lives led by some of the town's citizenry but led to only tenuous theories about the bombing.

What's ultimately revealed is the true depth of evil that occurred in Marshall that day. Every small town has dirty little secrets. This time, they were deadly.
