November 22, 1963 – the day President John F. Kennedy was shot – burns in retired FBI agent Ed Malloy’s mind. Tormented by the memory, a lifetime later, Malloy receives a mysterious letter from the woman who claims she saw what really happened that day in Dallas. Helena Storozhenko, the Babushka Lady, snapped a photo that would have changed everything.
The she vanished.
Malloy and Jack Doyle, a television journalist inextricably linked to the story, need each other to stop an assassin driven by the same evil. It all comes down to one place, one time, one bullet as they race to prevent history from repeating itself-more than fifty years after a president was slain, and Helena Storozhenko was the last Witness.
