This is the first Spenser book written after Parker’s death. For his other books where other authors have continued his characters, I couldn’t tell a difference in the writing style. I guess that is good, and it was the same for this one.
Spenser is hired by a 14 year old girl who needs his help to track down the person who murdered her mother four years earlier. Of course, Spenser figures it out with the help of his friends.
