cannot disagree with much of Steve Watson's review of _The Raleigh Legacy_ but I can answer his question about the identity of Jon L. Lellenberg. Jon's blurbable status derives primarily from the fact that he is the literary agent for Dame Jean Conan Doyle in the U.S., where the characters [Sherlock] Holmes and [Dr.] Watson are still protected under complex legal aspects of copyright and trademark that I cannot claim to understand.
