Finally - a book with Windsor Horne Lockwood III as the central character - and a promise for more! Coben gives us a few references to Myron - but not too many. Jessica Culver makes an appearance, as does the damn furnace from earlier books. But enough about the small references that make Coben fans smile but don’t hinder your experience if you are new to his work.
We start with Win delivering some typical Win style justice to an assistant basketball coach after the final game of the NCAA tournament. That story thread continues through the book - but is only a sub-plot. 
The main story involves unraveling the pieces of a story that involves a 1960’s anti-war group named the Jane Street Six - and what happened to the Six after a night in New York City when Molotov cocktails were thrown at a building - but a city bus crashed and innocent lives were lost. The six went underground - and were never heard from again until one of them is found murdered in his exclusive New York apartment. When investigating the police find a Vermeer painting owned by Win’s family but stolen from an exhibition at Haverford College. The Vermeer is hanging on the wall of the man’s bedroom - and in another room of his apartment is a suitcase. A suitcase with the Lockwood family crest and Win’s initials. 
Of course, because the dead man is part of long cold FBI case, Win is now asked to assist with the investigation. An investigation that seems to intersect with his cousin’s long ago abduction and stay in a place dubbed “the Hut of Horrors”. As Win starts to put the pieces together, he learns the real story of the estrangement between his father and his uncle (cousin Patricia’s father) - finds out what happened to all seven members of the Jane Street Six - and delivers some Win inspired justice.
His daughter Ema makes an appearance; and we learn the back story of what drove Win to develop his own style of vigilante justice. Very well done - looking forward to more books with Win.
