"Sheldon. Forty-three miles from London. Population seven hundred and thirty. Two beerhouses. Shut at ten."
"Has the establishment a name?"
"Tylney House. Enclosed. Stone wall all round it. Easy to get over in one part. All the other parts, broken glass at top."
"Character?"
"Difficult to get at. Population has no opinions. I should say, damned scoundrel."
"Why should you say so?"
"Impression."
"Is Dr. Peterssen always at home?"
"Seldom. Away for days together. Comes back. Stops for a day and a night. Goes away again next morning."
"Who takes care of Tylney House in his absence?"
