Recently discovered papers have proved beyond a shadow of a doubt that the great detective Sherlock Holmes had a son. And later, a grandson. That grandson's name was Creighton. From boyhood on, it was Creighton Holmes's ambition to follow in the hallowed footsteps of his illustrious forebear. How brilliantly he succeeded, and what baffling mysteries and stunning solutions filled his casebook, now at last are revealed in adventures that take us back to Baker Street and the eternal war against masters of crime and monsters of evil.
While I agree that the premise and much of the material is inconsistent with known Holmesian lore, this was written about 1978-1979. As far as I know, it is Mr Hubbell's only published work. August Derleth's Solar Pons stories are better pastiches of Sherlock.
An entertaining read, although I find the premise - that Sherlock Holmes was briefly married, lost his wife in childbirth and turned the child (Creighton Holmes' father) over to the mother's parents, essentially abandoning him - to be completely implausible, in light of what we know about his integrity and ethics. The stories are generally pretty good, except for a couple of quibbles: 1) in the one where the suicide note was faked, as far as I could find, he never explains how the killer got the victim's signature either on the note or a blank piece of paper; and 2) in the last story, set in the US, he has the prosecution spring a very important piece of evidence on the defense in the middle of a trial, which would invalidate the trial then and there. I'm not sure how far back the requirements for discovery go, but these stories have airplanes and television, so they're obviously set in the second half of the 20th century.
If I could give a zero rating I would. This is very poor-man's Holmes pastiche, with weak characterization at best, both for the leads and the supporting characters, stereotypical accents and dialogue, dull crime detection, and thinly-disguised attempts to rewrite some classic Sherlock Holmes quotations. I hope the writer gave up trying to do more of these stories.
