Then maturer consideration came and forced him to acknowledge that it was indeed devotion that had swayed Adele Bernauer, devotion to her master more than to her mistress. This was hardly to be wondered at. But she had not thought what might come from her revelations, what had come of them. For now her pet, the baby who had once lain in her arms, the handsome, gifted man whom she adored with more than the love of many a mother for the child of her own blood, was under the shadow of hideous disgrace and doom, was the just prey of the law for open trial and condemnation as a murderer.

Muller sighed deeply once more and then came one of those moments which he had spoken of to the unhappy woman that very day. He felt like cursing the fatal gift that was his, the gift to see what was hidden from others, this something within him that forced him relentlessly onward until he had uncovered the truth, and brought misery to many.

Muller need not do anything, he need simply do nothing. Not a soul besides himself suspected the dwellers in the Thorne mansion of any connection with the murder. If he were silent, nothing could be proven against Knoll after all, except the robbery which he himself had confessed. Then the memory of the terror in the tramp’s little reddened eyes came back to the detective’s mind.

“A human soul after all, and a soul trembling in the shadow of a great fear. And even he’s a better man than the blackmailer who was killed. A miscarriage of justice will often make a criminal of a poor fellow whose worst fault is idleness.” Muller’s face darkened as the things of the past, shut down in the depths of his own soul, rose up again. “No; that’s why I took up this work. Justice must be done—but it’s bitter hard sometimes. I could almost wish now that I hadn’t seen that face at the gate.”

CHAPTER X. MULLER RETURNS TO THE THORNE MANSION

It was striking eight as Muller came out of a cafe in the heart of the city. He had been in there but a few moments, for his purpose was merely to look through the Army lists of the current year. The result of his search proved the correctness of his conclusions.

There was a Lieutenant Theobald Leining in the single infantry regiment stationed at Marburg.

Muller took a cab and drove to the main telegraph office. He asked for the original of the telegram which had been sent that afternoon to the address; “Herbert Thorne, Hotel Danieli, Venice.” This closed the circle of the chain.

The detective re-entered his waiting cab and drove back to Hietzing. He told the driver to halt at the corner of the street on which fronted the Thorne mansion and to wait for him there. He himself walked slowly down the quiet Street and rang the bell at the iron gate.
