He called Inspector Damarell.
"When this is compared with the plaster casts taken at Foggintor, you'll find it's the same boot," he said. "That's no surprise, of course, but it proves probably that we are dealing with the same man."
"And he'll use the same means to vanish into thin air that he did six months ago," prophesied the other. "You mark me, Brendon, this is not one man's work. There's a lot hid under this job that hasn't seen light—just as there was under the last. It's very easy to say, because we can't find a motive, the man's mad. That's the line of least resistance; but it don't follow by a long sight that it's the right line. Here's a chap has lured his brother to death, and very cunning he's been about it. He's pitched a yarn and then, after a promise to turn up, he changes his mind and makes a new plan altogether by which old Ben Redmayne is put entirely in his power. Then—"
"But who was to know he meant mischief? We had facts to deal with. Mrs. Pendean herself had seen and spoken to him; so had Doria. In the case of the lady, at any rate, all she said was above suspicion. She hid nothing; she behaved like a Christian woman, wept at the spectacle of his awful misery, and brought his message to his brother. Then sudden, panic fear overtook the man at the last moment—natural enough—and he begged Bendigo Redmayne to see him in his hiding-place alone. It rang true as a bell. For myself I had not a shadow of suspicion."
"That's all right," admitted Damarell, "and I'm not one who pretends to be wise after the event. But, as I told you before, I thought it a mistake to suspend our search and take the matter out of professional hands just when we were safe to nab him. You were in command and we obeyed, but whatever the murderer had to say would as well have been said to us as to his brother—and better; because in any case he might have tempted a brother to break the law for him. Now there's more innocent blood been shed and a damned, dangerous criminal—mad or sane—is still at large. Most likely more than one. However, it is not much use jawing, I grant you. What we've got to do is to catch them—if we can."
Brendon made no reply to this speech. He was vexed, yet knew that he had heard little more than the truth.
He examined the plateau and showed again where some round object had pressed the earth and where a man had sat beside it. From this spot it was not possible to dispose of a body in the sea. Beneath it extended a fall of a hundred feet to broken ground, which again gave by sloping shelves to the water. Had a corpse been thrown over here, it must have challenged their sight beneath; and yet from this standpoint no sign of the vanished man or his burden appeared. But the zigzag path to the cliff top revealed neither any evidence of a weight being dragged upward nor the impression of the iron-shod foot. Fresh footprints there were, but they had been made by Brendon and Doria on the previous night. Now the police ascended, making careful examination of every turn in the way, and finally reached the summit a little after noon. It was a dizzy height, beetling over the sea beneath; but crags and buttresses broke out from the six hundred feet of precipice and any object thrown over from the crest of Hawk Beak Hill must have been arrested many times in its downward progress.
Inspector Damarell stopped to rest and flung himself panting on the close sward at the crown of the cliff.
"What do you think?" he asked Brendon; and the other having made a careful examination of the ground around them and scanned the peaks and ledges beneath, answered:
"He never came here—at any rate not until he had disposed of the body. It's the broken ground under the plateau we must search. There may be a way down that he knew. I guess he threw the body over, then scrambled down himself and covered it deep with stones. It's surely there—for the simple reason that it can't be anywhere else. We should have found out if he'd brought it to the top. And in my judgment, even if he wanted to do so, he would have lacked the physical strength. He must have spent himself getting it to the plateau, however strong he is, and then found that he could do no more. The body, therefore, should be hidden in the rocks below the plateau."
