There was only one thing to be done: she must go up to his apartment, and have something to eat, and then she must rest. In the meantime they would make some plan in order to explain her absence.

The porter's wife might have been of some use, if she could have been trusted with what must for ever remain a dead secret, namely, that Sabina had spent the night in Malipieri's rooms; for that would be the plain fact to-morrow morning. What had happened to Sassi and Masin was a mystery, but it was inconceivable that either of them should have been free to act during the past eight or nine hours and should have made no effort to save the two persons to whom they were respectively devoted as to no one else in the world.

Exhausted though he was, Malipieri would have gone down into the cellars at once to try and find some trace of them, if he had not felt that Sabina must be cared for first; and moreover he was sure that if he found them at all, he should find them both dead.

All this had been clear to him before he had at last succeeded in bringing her out into the open air.

"There is no help for it," he whispered, "you must come upstairs. Do you think you can walk so far?"

"Of course I can!" she answered, straightening herself bravely. "I am not at all tired."

Nevertheless she gladly laid her hand on his aching arm, and they both walked cautiously along the paved gutter that separated the wall from the gravel, for their steps would have made much more noise on the latter. All was quiet, and they reached Malipieri's door, by the help of a wax light. He led her in, still carrying the match, and he shut the door softly after him.

"At least," Sabina said, "no one can hear us here."

"Hush!"

He suspected that Toto must have got out, but was not sure. After lighting a candle, he led the way into his study, and made Sabina sit down, while he went back. He returned in a few moments, having assured himself that Toto had escaped by the window, and that Masin was not in, and asleep.
