Read this last summer before I began the Spenser series but remember it well. Both Hawke and Susan, especially, play important characters. This, of course, was before I knew Susan very well so she was simply Spenser's friend. Didn't have the background information that I have developed from reading the series.
This was a good read though but the ending kind of flopped...worth the time spent reading it although Spenser was simply a P.I. at the time. Not the SPENSER I now know!
