He took it that he was leaving the Castle by one of the library windows.

Well, it was no business of his.
At a few minutes past eight the next morning he was roused from the deep dreamless sleep which follows good food and good wine well digested, by a loud knocking on his door.

It was not the loud, steady and prolonged knocking which the third housemaid found necessary to wake him.

It was more vigorous and more staccato and jerkier.

Also, a voice was calling loudly: "Mr.Manley, sir! Mr.Manley! Mr.Manley!" For all the noise and insistence of the calling Mr.Manley did not awake quickly.
