Why yes, yes there
is a mystery novel based on the T.J. Wise forgeries. Julian Symons'
Bland Beginning (or as it is sometimes titled,
Bland Beginnings), first published in 1949, is a schlock-filled romp (think P.G. Wodehouse plus Agatha Christie, but not all that well written). But it's full of interesting details about the Wise forgeries and Carter and Pollard's enquiries into them, making it absolutely worth the few hours it takes to read it.
