The Spy in the City of Books — Stephen O'Connor

The past has caught up with Martin LeBris. During World War II, he served the Office of Strategic Services as a spy and saboteur in Lyon, France. Nearly sixty years later, Lowell cop Gerry O'Neil is trying to unravel the mystery of why an assassin is stalking LeBris. The answer to that question lies buried in the dark days of Nazi Occupation, and in the unforgiving memory of The Spy in the City of Books.
