Walker heard him climb over the fence and then followed as far as the verandah. In the still night the rustle and swish of the undergrowth came quite clearly to his ears. The sound ceased, and a few minutes afterwards the muffled crack of a pistol-shot broke the silence like the tap of a hammer. The swamp, as Walker prophesied, told no tales. Mrs. Hatteras gave the one explanation of her husband’s disappearance that she knew, and returned broken-hearted to England. There was some loud talk about the self-sacrificing energy which makes the English a dominant race, and there you might think is the end of the story.

But some years later Walker went trudging up the Ogowe River in Congo Français. He travelled as far as Woermann’s factory in Njob Island, and, having transacted his business there, pushed up stream in the hope of opening the upper reaches for trade purposes. He travelled for a hundred and fifty miles in a little sternwheel steamer. At that point he stretched an awning over a whale-boat, embarked himself, his banjo and eight blacks from the steamer, and rowed for another fifty miles. There he ran the boat’s nose into a clay cliff close to a Fan village, and went ashore to negotiate with the chief.

There was a slip of forest between the village and the river banks, and while Walker was still dodging the palm creepers which tapestried it he heard a noise of lamentation. The noise came from the village, and was general enough to assure him that a chief was dead. It rose in a chorus of discordant howls, low in note and very long drawn out—wordless, something like the howls of an animal in pain, and yet human by reason of their infinite melancholy.

Walker pushed forward, came out upon a hillock fronting the palisade which closed the entrance to the single street of huts, and passed down into the village. It seemed as though he had been expected. For from every hut the Fans rushed out towards him, the men dressed in their filthiest rags, the women with their faces chalked and their heads shaved. They stopped, however, on seeing a white man, and Walker knew enough of their tongue to ascertain that they looked for the coming of the witch-doctor. The chief, it appeared, had died a natural death, and since the event is of sufficiently rare occurrence in the Fan country, it had promptly been attributed to witchcraft, and the witch-doctor had been sent for to discover the criminal. The village was consequently in a lively state of apprehension, for the end of those who bewitch chiefs to death is not easy. The Fans, however, politely invited Walker to inspect the corpse. It lay in a dark hut, packed with the corpse’s relations, who were shouting to it at the top of their voices on the off-chance that its spirit might think better of its conduct and return to the body. They explained to Walker that they had tried all the usual varieties of persuasion. They had put red pepper into the chief’s eyes while he was dying; they had propped open his mouth with a stick; they had burned fibres of the oil-nut under his nose. In fact they had made his death as uncomfortable as possible, but none the less he had died.

The witch-doctor arrived on the heels of the explanation, and Walker, since he was powerless to interfere, thought it wise to retire for a time. He went back to the hillock on the edge of the trees. Thence he looked across and over the palisade, and had the whole length of the street within his view.

The witch-doctor entered in from the opposite end to the beating of many drums. The first thing Walker noticed was that he wore a square-skirted eighteenth century coat and a tattered pair of brocaded knee breeches on his bare legs; the second was that he limped—ever so slightly. Still he limped, and with the right leg. Walker felt a strong desire to see the man’s face, and his heart thumped within him as he came nearer and nearer down the street. But his hair was so matted about his cheeks that Walker could not distinguish a feature. “If I was only near enough to see his eyes,” he thought. But he was not near enough, nor would it have been prudent for him to have gone nearer.

The witch-doctor commenced the proceedings by ringing a handbell in front of every hut. But that method of detection failed to work. The bell rang successfully at every door. Walker watched the man’s progress, watched his trailing limb, and began to discover familiarities in his manner: “Pure fancy,” he argued with himself. “If he had not limped I should have noticed nothing.”

Then the doctor took a wicker basket, covered with a rough wooden lid. The Fans gathered in front of him; he repeated their names one after the other, and at each name he lifted the lid. But that plan appeared to be no improvement, for the lid never stuck. It came off readily at each name. Walker, meanwhile, calculated the distance a man would have to cover who walked across country from Bonny River to the Ogowe, and he reflected with some relief that the chances were several thousand to one that any man who made the attempt, be he black or white, would be eaten on the way.

The witch-doctor turned back the big square cuffs of his sleeves as a conjurer will do, and again repeated the names. This time, however, at each name he rubbed the palms of his hands together. Walker was seized with a sudden longing to rush down into the village and examine the man’s right forearm for a bullet mark. The longing grew on him. The witch-doctor went steadily through the list. Walker rose to his feet and took a step or two down the hillock, when, of a sudden, at one particular name, the doctor’s hands flew apart and waved wildly about him. A single cry from a single voice went up out of the group of Fans. The group fell back and left one man standing alone. He made no defence, no resistance. Two men came forward and bound his hands and his feet and his body with tie-tie. Then they carried him within a hut.

“That’s sheer murder,” thought Walker. He could not rescue the victim, he knew. But he could get a nearer view of the witch-doctor. Already the man was packing up his paraphernalia. Walker stepped back among the trees, and running with all his speed, made the circuit of the village. He reached the further end of the street just as the witch-doctor walked out into the open.
