“Nothing, except that they were probably killed.”

“You should learn to draw inferences. It is a useful art, especially in Africa. It suggests to me that, if you are right, the deed was not done by natives, who would never take the trouble to bury the dead. Arabs, on the contrary, might do so, especially if there were any bastard Portuguese among them who called themselves Christians. But whatever happened must have been a long while ago,” and I pointed to a self-sown hardwood tree growing from the mound which could scarcely have been less than twenty years old.

We returned to the house to find that our meal was ready. Hassan had asked us to dine with him, but for obvious reasons I preferred that Sammy should cook our food and that he should dine with us. He appeared full of compliments, though I could see hate and suspicion in his eye, and we fell to on the kid that we had bought from him, for I did not wish to accept any gifts from this fellow. Our drink was square-face gin, mixed with water that I sent Hans to fetch with his own hands from the stream that ran by the house, lest otherwise it should be drugged.

At first Hassan, like a good Mohammedan, refused to touch any spirits, but as the meal went on he politely relented upon this point, and I poured him out a liberal tot. The appetite comes in eating, as the Frenchman said, and the same thing applies to drinking. So at least it was in Hassan’s case, who probably thought that the quantity swallowed made no difference to his sin. After the third dose of square-face he grew quite amiable and talkative. Thinking the opportunity a good one, I sent for Sammy, and through him told our host that we were anxious to hire twenty porters to carry our packages. He declared that there was not such a thing as a porter within a hundred miles, whereon I gave him some more gin. The end of it was that we struck a bargain, I forget for how much, he promising to find us twenty good men who were to stay with us for as long as we wanted them.

Then I asked him about the destruction of the mission station, but although he was half-drunk, on this point he remained very close. All he would say was that he had heard that twenty years ago the people called the Mazitu, who were very fierce, had raided right down to the coast and killed those who dwelt there, except a white man and his wife who had fled inland and never been seen again.

“How many of them were buried in that mound by the church?” I asked quickly.

“Who told you they were buried there?” he replied, with a start, but seeing his mistake, went on, “I do not know what you mean. I never heard of anyone being buried. Sleep well, honoured lords, I must go and see to the loading of my goods upon the Maria.” Then rising, he salaamed and walked, or rather rolled, away.

“So the Maria hasn’t sailed after all,” I said, and whistled in a certain fashion. Instantly Hans crept into the room out of the darkness, for this was my signal to him.

“Hans,” I said, “I hear sounds upon that island. Slip down to the shore and spy out what is happening. No one will see you if you are careful.”

“No, Baas,” he answered with a grin, “I do not think that anyone will see Hans if he is careful, especially at night,” and he slid away as quietly as he had come.
