A curious manifestation on the Strand

As the green comet looms ever-nearer in the sky and the world gets stranger, the Fellows of the Royal Mythological Society (Cyril Clattercut and Bampton Bromfield; that's them above) are busy answering queries about extraterrestrial etiquette, fairy faux pas, and how to live with a minotaur next door. You can read their collected correspondence in A Minotaur At The Savoy, which for this month only is priced at just 99 cents for more than fifty mini-stories like this:

Dear perfessors

I hope that you may help me with my Trouble and do not object to a letter from one as does not know you. I have the agreeable position of regular employment at a public house by the Strand, name of The Three Gypsies. My duties there in the main being the stabling of horses, polishing brasses, & co. I also do in the taprooms and some private bedrooms that are kept for travellers, though not so frequent as in former days, now that the coach stand is not there no more. In the morning I rake out the fires and carry the ashes in a pail, which I have been in the habit of tipping down the drain that is in the street near the entrance to the yard. Only the other morning I went out that way and saw what had the look of two sooty, or I should say ashen, footprints on the pavement outside. Scuffing at these with my foot had no effect to remove them, and thinking no more I went and poured the ashes down the drain as per usual. Then on the next day I found two bare feet standing there. Just the plain feet, you understand, and not with no body above them, the feet being grey and looking to my eye to be made of ashes. Subsequent to that, having visited the drain on my purpose some other times, the feet have now been joined by ankles and the lower part of the legs, that is the calf. Mr Bardley, him being the landlord, says not to be tipping the ashes that way no more, but I have become quite driven with Curiosity to find out what will come. Today I tipped out another pail of ashes and in the morrow I’m in expectation of a pair of knees. Do you gents think this is advisable, or is Mr Bardley right?

Yours, Joe Gammock, Raven Row E1

Dr Clattercut replies: Mr Gammock, I have no direct experience of exactly such a phenomenon as you describe, but I implore you to consider all the ways that it could turn out if you continue as you have. One does not have to be an avid reader of the works of Mr Bram Stoker to foresee something rather chilling. There are many bad endings to the story and few good ones.

Prof Bromfield: Hmm. You do not say as much in your letter, but I surmise that the pedal extremities in question are feminine, and reasonably shapely. For once I have to agree with Clattercut. If this goes on, Mr Gammock, I feel it could be a case of curiosity killing the cat.
