[CHAPTER IV]
THE HOUSE OF SHADOWS
Constable Roberts did "come on" and at a speed highly commendable, considering his portly build. Cleek, passing the long French windows through which he had obtained entry but an hour before, stopped to ascertain that they, too, were now bolted and barred.
Snapping on their electric torches they tore up the short flight of steps leading to the front door.
"Someone has made good use of their time," Cleek whispered, as he thought how easily he had entered with Lady Margaret such a short while before. "There's no use trying to force this door and the windows are now shuttered and barred. The only thing to do is to try knocking them up."
A second later Mr. Roberts sent a valiant peal resounding through the house and both men listened tensely for any response. One, two, perhaps five minutes passed; the echoes of their blows had died away into silence, and the flash of their torches showed to each of them only the other's strained expectant face. Neither eye nor ear could detect any signs of movement within.
"How we're to get in beats me," said Constable Roberts with a frown puckering his bushy brows. "We'll have to break in, in the name of the law."
And as though that very name had in itself something of the supernatural, there came a sound, a rustle, a step within the house, and the nerves of both men were near to snapping point. They stood a moment listening, while the harsh grating of bolts being withdrawn into their sockets came to their ears, and in another second the great door swung slowly back upon its hinges. The mellow radiance of lamps streamed out and flung a circle of light round them. As it did so a little gasp of astonishment came from both men, for in the doorway, gazing out on them in dignified reproof, stood an immaculate butler. Their hearts seemed for a moment to cease beating and they stared in dumb amazement.
