Chicago, September 1964. Beatlemania sweeps the nation, the Vietnam War looms, and the Warren Commission prepares to blame a “lone-nut" assassin for the killing of President John F. Kennedy. But as the post-Camelot era begins, a suspicious outbreak of suicides, accidental deaths, and outright murders decimates assassination witnesses. When Nathan Heller and his son are nearly run down on a city street, the private detective wonders if he himself...

"In Do No Harm, Heller takes on the Sam Sheppard case-a young doctor is startled from sleep and discovers his wife brutally murdered. He claims that a mysterious intruder killed his wife. But all the evidence points to a disturbed husband who has grown tired of married life and yearned to be free at all costs. Sheppard is swiftly convicted and sent to rot in prison. Just how firm was the evidence...and was it tampered with to fit a convenient narrative...

It began with John F. Kennedy in 1963. Then Malcolm X in 1965. Martin Luther King in April 1968.

And who sent them?
