When next I found a place to insert myself, I discovered the resident in the manse’s foyer, in conversation with a traveler. Keeping myself out of his sightlines, I flew to a spot high in a corner where a roof beam passed through the stone of the outer wall, and settled myself to watch and listen. The resident received almost no visitors — only the invigilant, he of the prodigious belly and eight varieties of scowl, and the steagle knife.

I rarely bothered to attend when the invigilant visited, conserving my energies for whenever my opportunity should come. But this stranger was unusual. He moved animatedly about the room in a peculiar bent-kneed, splay-footed lope, frequently twitching aside the curtain of the window beside the door to peer into the darkness, then checking that the beam that barred the portal was well seated.

“The creature cannot enter,” the resident said. “Doorstep and lintel, indeed the entire house and walled garden, are charged with Phandaal’s Discriminating Boundary. Do you know the spell?”

The stranger’s tone was offhand. “I am familiar with the variant used in Almery. It may be different here.”

“It keeps out what must be kept out; your pursuer’s first footfall across the threshold would draw an agonizing penalty.”

“Does the lurker know this?” said the visitor, peering again out the window.
