She showed him the scribbled note which M. Fournier had brought; she told him M. Fournier's story; how that Ralph had run guns and ammunition from England into Morocco on board the _Tarifa_; how that he had been kidnapped between M. Fournier's villa and the town-gate; how that he was not held to ransom, since no demand for ransom had come to the little Belgian; and finally how that it was impossible to apply for help to the Legation, since Ralph was already guilty of a crime, and would only be rescued that way in order to suffer penal servitude in England. "What a coil to unravel!" said Charnock. "I know some Arabic. I could go to Morocco. I went there once, but only to Tangier. But Morocco? How shall one search Morocco without a clue?" He rested his chin upon his hand, and stared gloomily at the wall. Miranda was careful not to interrupt his reflections. If there was a way out, she confidently relied upon this man to find it. Once she shivered, and Charnock looked inquiringly towards her. She was gazing at the soiled note which lay beneath her eyes upon the table, and saw again the picture of Ralph being beaten inland under the sun. She began to recall his acts and words, that she might make the best of them; she fell to considering whether she had not herself been in a measure to blame for the shipwreck of their marriage. And so, thinking of such matters, she absently hummed over a tune, a soft plaintive little melody from an _opéra-bouffe_. She ended it and hummed it over again; until it came upon her that Charnock had been silent for a long time, and she looked up from the note into his face. He was not thinking out any plan. He was watching her with a singular intentness, his head thrust forward from his shoulders, his face very strained. It seemed that every fibre of his body listened and was still, so that it might hear the better. "Who taught you that tune?" he asked in a voice of suspense. "Ralph," said she, in some surprise at the question; "at least I picked it up from him." And Charnock fell back in his chair; he huddled himself in it, he let his chin drop upon his breast. He sat staring at her with eyes which seemed suddenly deep-sunk in a face suddenly grown white. And slowly, gradually, it broke in upon Miranda that he held the clue after all, that that tune was the clue, that in a word Charnock knew how Ralph had disappeared. "You know!" she cried in her elation. "You know! Oh, and I sent you away yesterday! What if you had gone! Only to think of it! You know! That tune has given you the clue? It was Ralph's favourite! You heard it--when? Where? Tell me!" To her eager, joyous questions Charnock was silent. He did not move. He still sat huddled in his chair, with his chin fallen on his breast, and his eyes fixedly staring at her. Miranda's enthusiasm was chilled by his silence; it was succeeded by fear. She became frightened; she picked up the note and held it out to him and bade it speak for her.
