“The lady has some one with her,” said the portress.

“Oh? Well, show the other person in as well.”

Clarisse Mergy entered at once and introduced the gentleman with her, a gentleman in a black frock-coat, which was too tight for him and which looked as though it had not been brushed for ages. He was shy in his manner and seemed greatly embarrassed how to dispose of his old, rusty top-hat, his gingham umbrella, his one and only glove and his body generally.

“M. Nicole,” said Clarisse, “a private teacher, who is acting as tutor to my little Jacques. M. Nicole has been of the greatest help to me with his advice during the past year. He worked out the whole story of the crystal stopper. I should like him, as well as myself—if you see no objection to telling me—to know the details of this kidnapping business, which alarms me and upsets my plans; yours too, I expect?”

Prasville had every confidence in Clarisse Mergy. He knew her relentless hatred of Daubrecq and appreciated the assistance which she had rendered in the case. He therefore made no difficulties about telling her what he knew, thanks to certain clues and especially to the evidence of the portress.

For that matter, the thing was exceedingly simple. Daubrecq, who had attended the trial of Gilbert and Vaucheray as a witness and who was seen in court during the speeches, returned home at six o’clock. The portress affirmed that he came in alone and that there was nobody in the house at the time. Nevertheless, a few minutes later, she heard shouts, followed by the sound of a struggle and two pistol-shots; and from her lodge she saw four masked men scuttle down the front steps, carrying Daubrecq the deputy, and hurry toward the gate. They opened the gate. At the same moment, a motor-car arrived outside the house. The four men bundled themselves into it; and the motor-car, which had hardly had time to stop, set off at full speed.

“Were there not always two policemen on duty?” asked Clarisse.

“They were there,” said Prasville, “but at a hundred and fifty yards’ distance; and Daubrecq was carried off so quickly that they were unable to interfere, although they hastened up as fast as they could.”

“And did they discover nothing, find nothing?”

“Nothing, or hardly anything.... Merely this.”
