He reached the scene of the killing and made prompt inquiry. None had seen the face of the secret man save the watchman—and he was dead. As for the women—the villagers flapped their arms hopelessly. Who could say from what nation, from what tribes, Olandi stole his women?

One, so other inmates of Olandi's house said, was undoubtedly Ochori; as to the other, none knew her, and she had not spoken, for, so they said, she loved the dead man and was a willing captive.

This Olandi had hunted far afield, and was a hurricane lover and a tamer of women; how perfect a tamer Sanders discovered, for, as the Isisi saying goes, "The man who can bribe a woman's tongue could teach a snake to grind corn."

In a civilised country he would have found written evidence in the chief's hut, but barbarous man establishes no clues for the prying detective, and he must needs match primitive cunning with such powers of reason and instinct as his civilisation had given to him.

A diligent search of the river revealed nothing. The river had washed away the marks where the canoes had been beached. Sanders saw the bodies of both men who had fallen without being very much the wiser. It was just before he left the village that Abiboo the sergeant made a discovery.

There is a certain tree on the river with leaves which are credited with extraordinary curative powers. A few paces from where the watchman fell such a tree grew.

Abiboo found beneath its low branches a number of leaves that had been newly plucked. Some were stained with blood, and one bore the clear impression of a palm.

Sanders examined it carefully. The lines of the hand were clearly to be seen on the glossy surface of the leaf, and in the centre of the palm was an irregular cut, shaped like a roughly-drawn St. Andrew's Cross.

He carefully put the leaf away in his safe and went on to pursue his inquiries.

Now, of all crimes difficult to detect, none offers such obstacles as the blood feud which is based on a woman palaver.
