As the car passed him, he swung himself aboard again; and Sir Clinton drove up to near the house.
“We'll get down here, I think, and walk the rest,” he proposed, switching off his engine. “Let's see. Curtains all drawn. . . . Hullo! One of the small panes of glass on that front window has been smashed, just at the lever catch. You owe an apology to Mr. Justice, Inspector, I think. He's not brought us here to an absolute mare's nest, at any rate. There's been housebreaking going on.”
Followed by the others, he walked over to the damaged window and examined it carefully.
“No foot-prints or anything of that sort to be seen,” he pointed out, glancing at the window-sill. “The window's been shut, apparently, after the housebreaker got in—if he did get in at all. That would be an obvious precaution, in case the open window caught someone's eye.”
He transferred his attention to the casement itself. It was a steel-framed one, some four feet high by twenty inches wide, which formed part of a set of three which together made up the complete window. Steel bars divided it into eight small panes.
“The Burglar's Delight!” Sir Clinton described it scornfully. “You knock in one pane, just like this; then you put your hand through; turn the lever-fastener; swing the casement back on its hinges—and walk inside. There isn't even the trouble of hoisting a sash as you have to do with the old-fashioned window. Two seconds would see you inside the house, with only this affair to tackle.”
He glanced doubtfully at the lever handle behind the broken glass.
“There might be finger-prints on that,” he said. “I don't want to touch it. Just go round to the front door, Inspector, and see if it's open by any chance. If not, we'll smash the glass at the other end of this window and use the second casement to get in by, so as not to confuse things.”
When the Inspector had reported the front door locked, the Chief Constable carried out his proposal; the untouched casement swung open, and they prepared to enter the room, which hitherto had been concealed from them by the drawn curtains. Sir Clinton led the way, and as he pushed the curtain out of his road, his companions heard a bitten-off exclamation.
“Not much of a mare's nest, Inspector,” he continued in a cooler tone. “Get inside.”
