“Oh, this has all been prepared a long while ago. But now I’m really on their track. And after all, I haven’t really lost any time. Dieusy wasted no time in making inquiries in Sureau Street; he’s been working all this side of the house.”
Guerchard drew up the blinds, opened the shutters, and let the daylight flood the dim room. He came back to the fireplace and looked down at the heap of bricks, frowning:
“I made a mistake there,” he said. “I ought to have taken those bricks down carefully, one by one.”
Quickly he took brick after brick from the pile, and began to range them neatly against the wall on the left. The Duke watched him for two or three minutes, then began to help him. It did not take them long, and under one of the last few bricks Guerchard found a fragment of a gilded picture-frame.
“Here’s where they ought to have done their sweeping,” he said, holding it up to the Duke.
“I tell you what,” said the Duke, “I shouldn’t wonder if we found the furniture in this house still.”
“Oh, no, no!” said Guerchard. “I tell you that Lupin would allow for myself or Ganimard being put in charge of the case; and he would know that we should find the opening in the chimney. The furniture was taken straight out into the side-street on to which this house opens.” He led the way out of the room on to the landing and went down the dark staircase into the hall. He opened the shutters of the hall windows, and let in the light. Then he examined the hall. The dust lay thick on the tiled floor. Down the middle of it was a lane formed by many feet. The footprints were faint, but still plain in the layer of dust. Guerchard came back to the stairs and began to examine them. Half-way up the flight he stooped, and picked up a little spray of flowers: “Fresh!” he said. “These have not been long plucked.”
“Salvias,” said the Duke.
“Salvias they are,” said Guerchard. “Pink salvias; and there is only one gardener in France who has ever succeeded in getting this shade—M. Gournay-Martin’s gardener at Charmerace. I’m a gardener myself.”
“Well, then, last night’s burglars came from Charmerace. They must have,” said the Duke.
