There was a crowd in the vestibule of the theatre, and she saw Keith standing in the corner, looking as pale as death, talking to a man.

She went up to congratulate him on the success of the performance, but something in his face made her afraid.

"What's the matter, Keith?" she asked, touching him.

"Hush!" he said in a hoarse whisper, "don't say a word--I'm arrested."

"Arrested! What for?" she gasped.

The man standing next to Keith interposed.

"For the murder of Jacob Lazarus," he said in a low voice.

Eugénie closed her eyes with a sensation of horror, and caught hold of the wall for support. When she opened her eyes again, Keith and the detective had both vanished.

"Arrested for the murder of Lazarus!" she muttered. "My God! it can't be true!"
