"Sorry, it would be nearly impossible for anyone to be more clueless than I am. I believe that I'm supposed to ask for Esme?" You say, producing the business card and handing it over to him. He shifts his position so that he can get his right arm through the door and grabs the card. He looks it over in an odd sort of way, as though it is some sort of foreign insect that he is examining, turning it over and over and even looking at the edges of it. After a few moments he grunts and hands it back. He shoves the door the rest of the way open and then jerks his head towards the interior. You notice he has an old military sabre dangling from his belt. It looks quite out of place considering the rest of his porter-like uniform.
"Esme is down in the records room. Follow the signs. Try nothing funny, lad, else you'll regret it."
You consider asking what he means by that but you have the distinct feeling he won't explain himself. You're about to head in when you remember something.
"By the way," You say and point at one of the spectral fish things gliding by just overhead, "Do you see that?"
The man's eyes narrow and you feel the intensity of his stare ratchet up by a few orders of magnitude. His eyes...well the right eye at least...darts rapidly from you, up to where you're indicating and back down in a fraction of a second.
"No." He says slowly, "Is there something I ought to be seeing?" There's a definite tension to him now and you notice how his right hand has very slightly changed orientation, so that he could more easily grab the handle of his sabre.
