Montague Rhodes James, who used the publication name M. R. James, was an English mediaeval scholar and provost of King's College, Cambridge (1905–1918), and of Eton College (1918–1936). He is best remembered for his ghost stories. In his stories, James's protagonists and plots tend to reflect his own antiquarian interests. Among the "antiquarian ghost stories", there is the "Casting the Runes"
"One chapter in particular struck me, in which he (Karswell) spoke of "casting the Runes" on people, either for the purpose of gaining their affection or of getting them out of the way--perhaps more especially the latter: he spoke of all this in a way that really seemed to me to imply actual knowledge. ...
By way of answer, Dunning had the episode in the Manuscript Room at the British Museum to relate. 'Then he did actually hand you some papers; have you examined them? No? because we must, if you'll allow it, look at them at once, and very carefully.'
They went to the still empty house--empty, for the two servants were not yet able to return to work. Dunning's portfolio of papers was gathering dust on the writing-table. In it were the quires of small-sized scribbling paper which he used for his transcripts: and from one of these, as he took it up, there slipped and fluttered out into the room with uncanny quickness, a strip of thin light paper. The window was open, but Harrington slammed it to, just in time to intercept the paper, which he caught. 'I thought so,' he said; 'it might be the identical thing that was given to my brother. You'll have to look out, Dunning; this may mean something quite serious for you.'
A long consultation took place. The paper was narrowly examined. As Harrington had said, the characters on it were more like Runes than anything else, but not decipherable by either man, and both hesitated to copy them, for fear, as they confessed, of perpetuating whatever evil purpose they might conceal. So it has remained impossible to ascertain what was conveyed in this curious message or commission. Both Dunning and Harrington are firmly convinced that it had the effect of bringing its possessors into very undesirable company. That it must be returned to the source whence it came they were agreed, and further, that the only safe and certain way was that of personal service; and here contrivance would be necessary, for Dunning was known by sight to Karswell. ...".
