"Show this card to the detectives at the door, and they'll pass you without a word." He pressed the card into her hand.
"But--but--this card ?" stammered Sonia.
"There's no time to lose," said the Duke.
"But this is madness," said Sonia.

"When Guerchard finds out about this card--that you--you--" "There's no need to bother about that," interrupted the Duke quickly.
"Where are you going to ?" "A little hotel near the Star.

I've forgotten the name of it," said Sonia.

"But this card--" "Has it a telephone ?" said the Duke.
"Yes--No.

555, Central," said Sonia.
"If I haven't telephoned to you before half-past eight to-morrow morning, come straight to my house," said the Duke, scribbling the telephone number on his shirt-cuff.
"Yes, yes," said Sonia.
