A Psalm of Abraham of That Which Was Visited upon Him

A prowler in the mansion of my blood!
I have not seen him, but I know his signs.
Sometimes I hear him meddling with my food,
Or in the cellar, poisoning my wines, ⁠—

Yet face to face with him I never come;
But by a foot print, by a book misplaced,
Or by the imprint of an inky thumb,
Or by the next day’s meal, a strange new taste,

I know that he has breached my household peace,
I know that somehow he has let him in.
Shall I fling open a window, and shout Police!
I dare not. He is of my kith and kin.
