On Sumuru

Stumbled across a tantalising hint that, even in 1945, the BBC recognised the Fu Manchu franchise for what it was. Apparently, they asked Sax Rohmer to develop a radio series for them -- but one which wouldn't insult the Chinese. (Unlike migrants, your allies in war are not dispensible.) The result was "Shadow of Sumuru", with its ambiguously Japanese protagonist. So near and yet so far. I'd like to get a solid source for this.

(Jon and I tried to watch The Million Eyes of Sumuru (1967), but even Riff Trax couldn't make it tolerable. Although MST3K, which is funnier and far less mean-spirited, might have been able to manage it.)
