This re-read pretty well, I was relieved to find (having the feeling that most of the mysteries I bought in the 90s should be dropped off at the local book exchange). Admittedly, part of the reason I still found it enjoyable was that it's set in Berkeley and San Francisco and deals with runaway and at-risk teens, thus takes me back to my days working in adolescent drug rehab in San Francisco (in a pleasant rather than appalling way).
