At the police station a car was waiting for him and in twenty minutes he had reached Foggintor.  Picking his way past the fishing pools and regarding the frowning cliffs and wide spaces of the quarry under a mournful mist, Mark proceeded to the aperture at the farther end.  Then he left the rill which ran out from this exit and soon stood by the bungalow.  It was now the dinner hour.  Half a dozen masons and carpenters were eating their meal in a wooden shed near the building and with them sat two constables and their superior officer.

Inspector Halfyard rose as Brendon appeared, came forward, and shook hands.

“Lucky you was on the spot, my dear,” he said in his homely Devon way.  “Not that it begins to look as if there was anything here deep enough to ask for your cleverness.”

Inspector Halfyard stood six feet high and had curiously broad, square shoulders; but his imposing torso was ill supported.  His legs were very thin and long, and they turned out a trifle.  With his prominent nose, small head, and bright little slate-grey eyes, he looked rather like a stork.  He was rheumatic, too, and walked stiffly.

“This here hole is no place for my legs,” he confessed.  “But from the facts, so far as we’ve got ’em, Foggintor quarry don’t come into the story, though it looks as if it ought to.  But the murder was done here—­inside this bungalow—­and the chap that’s done it hadn’t any use for such a likely sort of hiding-place.”

“Have you searched the quarries’?”

“Not yet.  ’Tis no good turning fifty men into this jakes of a hole till we know whether it will be needful; but all points to somewhere else.  A terrible strange job—­so strange, in fact, that we shall probably find a criminal lunatic at the bottom of it.  Everything looks pretty clear, but it don’t look sane.”

“You haven’t found the body?”

“No; but you can often prove murder mighty well without it—­as now.  Come out to the bungalow and I’ll tell you what there is to tell.  There’s been a murder all right, but we’re more likely to find the murderer than his victim.”

They went out together and soon stood in the building.

“Now let’s have the story from where you come in,” said Brendon, and Inspector Halfyard told his tale.

“Somewhere about a quarter after midnight I was knocked up.  Down I came and Constable Ford, on duty at the time, told me that Mrs. Pendean was wishful to see me.  I knew her and her husband very well, for they’d been the life and soul of the Moss Supply Depot, run at Princetown during the war.
