Uh, yeah. I'm excited. All I did was google Richard Stevenson on Amazon, looking for second-hand Strachey books, and there it was! It's called "The Last Thing I Saw," and it looks like Don's in it over his head - or at least up to his waist, according to Timmy.
Here it is in paperback from Amazon and
Here it is in ebook format from the publisher.
Snark city, here I come!
