And of course Miss Arthur assented.

Before leaving, Mr. Davlin arranged that the carriage should come for Miss Arthur the next day, and that a porter should immediately transfer their luggage to Oakley.

Then Mr. Percy stole on until he stood at the door of the wing. Satisfying himself that Davlin was actually within the forbidden room, he waited for nothing further, but glided quietly back to his own door, looking as imperturbable as ever and saying to himself:
