You have done your part." With a look of humble entreaty, she obeyed him.

Denzil, already observed by Glazzard, stepped forward.
"Do you know that man ?" he asked, pointing to Northway, who affected a study of some neighbouring work of art.
"I have met him," was the subdued answer.
It was necessary to speak so that attention should not be drawn hither.
Though profoundly agitated, Quarrier controlled himself sufficiently to use a very low tone.
"He has told an incredible story, Glazzard.

I sha'n't believe it unless it is confirmed by your own lips." "I have no doubt he has told the truth." Denzil drew back.
"But do you know _what_ he has said ?" "I guess from the way he addressed me--as Mr.Marks." Glazzard was deadly pale, but he smiled persistently, and with an expression of relief.
"You--_you_--betrayed us to him ?" "I did." Each could hear the other's breathing.
"Why did you do that ?" asked Denzil, the excess of his astonishment declaring itself in a tone which would have suited some every-day inquiry.

He could not speak otherwise.
"I can't tell you why I did it.

I'm not sure that I quite understand now.
