Most crimes, no doubt, were brought home because the criminal had made some incomprehensibly stupid mistake; incomprehensibly stupid, that is, by the standards of normal life. Nevertheless, Calladine was inclined to believe her. He looked at her. That she should have murdered was absurd. Moreover, she was not making a parade of remorse, she was not playing the unctuous penitent; she had yielded to a temptation, had got herself into desperate straits, and was at her wits' ends how to escape from them. She was frank about herself.
Calladine looked at the clock. It was nearly five o'clock in the morning, and though the music could still be heard from the ballroom in the Semiramis, the night had begun to wane upon the river.
"You must go back," he said. "I'll walk with you."
They crept silently down the stairs and into the street. It was only a step to the Semiramis. They met no one until they reached the Strand. There many, like Joan Carew in masquerade, were standing about, or walking hither and thither in search of carriages and cabs. The whole street was in a bustle, what with drivers shouting and people coming away.
"You can slip in unnoticed," said Calladine as he looked into the thronged courtyard. "I'll telephone to you in the morning."
"You will?" she cried eagerly, clinging for a moment to his arm.
"Yes, for certain," he replied. "Wait in until you hear from me. I'll think it over. I'll do what I can."
"Thank you," she said fervently.
He watched her scarlet cloak flitting here and there in the crowd until it vanished through the doorway. Then, for the second time, he walked back to his chambers, while the morning crept up the river from the sea.
