So, as established yesterday, there’s much more scope in Watson than there is in Holmes. The obvious question then becomes: So what do you do with this?
Take the simple cosmetic changes out of the equation — the casting of Lucy Liu as Dr. Joan Watson in the US series Elementary, for instance, easily one of the least disruptive changes it’s possible to get away with — and what you’re left with is the fact that Watson, being our entry into the Holmesiverse, is allowed to do anything that reflects the experience and perspective of the reader. As discussed yesterday, there are aspects of the character, the constants I referred to, that don’t become him — making him the proprietor of a burgeoning dog-walking business, or a respected scholar of nineteenth century Gothic poetry, or giving him a form of OCD which means he must always cross his legs in the opposite manner to Holmes unless it’s a Tuesday in which case…, etc — but let’s put this aside as given and look at the way certain authors have expanded on Watson without desecrating him beyond all recognition.
Lately I’ve read an unusually high concentration of Holmes pastiches — Caleb Carr’s The Italian Secretary (not good), Stephen King’s ‘A Doctor’s Case’ (not terrible), Colin Dexter’s ‘A Case of Mis-Identity’ (extremely good), Michael Kurland’s The Infernal Device (loadsa fun), Steve Hockensmith’s Holmes on the Range (fabulous) and a superb piece of unpublished fan fiction sent to me via email — and it’s made me realise that while Watson, and specifically the Watsonian voice, is vital in undertaking Holmes, no-one can quite agree what Watson is, how he should be written, and this makes him far and away the more interesting of the two men when it comes to analysis.
