Huh! Just finished this one -- really enjoyed it -- and I went into it expecting Holmesian inspiration, but I didn't really see any. To me, it's more of a Nero Wolfe inspired situation. (Although Wolfe is certainly a reaction to Holmes, so there's a lineage there.) But, regardless -- you were right, this is very fun, and I very much look forward to the next. (Cannot believe Bennett managed to write a mystery novel right on his first try. This man continues to surprise me.)
