Mmm... I haven't read any of Moore and Reppion's previous stuff. They also have Dracula and Doctor Who projects on the go. On their forum boards, Reppion advances Jose Farmer's Tarzan Alive and Neil Gaiman's Study in Emerald as examples of pastiche that he admires, which might suggest a radical approach. However, he also writes, "We'll be doing our best to keep things (more or less) as Mr. Doyle intended them."
