"Where did you see her last?" asked Norwood.
"At her own house in Park Lane."
"Did you leave her there?"
"No! she left me."
"Oh!" cried Dowker, a light breaking in on him, "now I understand--you changed clothes there, and she left the house first."
"She did--to go to Calliston's rooms."
"I thought so," said Norwood with a cry of triumph, "it was Lady Balscombe Desmond saw."
"Desmond! Desmond!" she echoed. "What has he to do with this?"
"Simply this--he is now in prison on a charge of murdering Lena Sarschine."
"I see you mistook my sister for me--but murder--I can't understand--I can't understand," and she pressed her hand across her forehead.
