In his book Haining also reproduced the headers from another story series in this volume, The Last of the Borgias, about a vigilante medico who bumps off undesirable people with undetectable poison. This series was written by one of the most interesting of the now forgotten fantasy writers, Fred M White. Aside from this rather surprising series about a murdering anti-hero - and indeed many others - Smith wrote several disaster stories about various dooms that might befall London, a yarn about killer trees in Meso-America [The Purple Terror] and one of my favourites, The Great White Moth.
In this tale - which appeared in Pearson's rival The Strand - adventurers try to make their fortune by securing exquisite and voluminous white feathers that would sell for a fortune to decorate ladies' hats. But, as you can guess from the title, they come not from birds but from monstrous moths. The gigantic insects live in a cave in (I think) darkest Africa, are worshipped (of course) by the locals and the plucky entrepreneurs get into all sorts of scrapes trying to secure a few plumes. I like it particularly because it could not have been written at any other time - the fashion for feathers, extensive parts of the world still unexplored, young men seeking to make their fortunes in exotic locations etc.
I'd LOVE to start reprinting some of this stuff. And one day I will.
