"I regret that the circumstances which have brought me here are of so singular and complicated a character as to prevent my giving you the full explanation to which you may consider yourself entitled. I am sorry that I should have sought refuge beneath your roof as I own I did; and the more so as I am compelled to ask you another favour--permission to leave that refuge by means of the back door."

She twirled round on her heels and faced him.

"The back door!"

"I presume there is a back door?"

"Certainly--only it leads to the front."

Again he bit his lip. His temper did not seem to be improving. The girl's tone, face, bearing, were instinct with scorn.

"Is there no means of getting away by the back without returning to the front?"

"Only by climbing a hedge and a fence on to the common."

"Perhaps the feat will be within my powers--if you will allow me to try."

"Allow you to try! And is it possible that you forced your way into the house on the pretence of seeking lessons in music, when your real motive was to seek an opportunity of evading pursuit by means of the back door?"
