Here's a short story:

CHAPTER SIX 

We said no more about Heyst on that occasion, and it so happened that I did not meet Davidson again for some three months. When we did come together, almost the first thing he said to me was: 

"I've seen him." 

Before I could exclaim, he assured me that he had taken no liberty, that he had not intruded. He was called in. Otherwise he would not have dreamed of breaking in upon Heyst's privacy. 

"I am certain you wouldn't," I assured him, concealing my amusement at his wonderful delicacy. He was the most delicate man that ever took a small steamer to and fro among the islands. But his humanity, which was not less strong and praiseworthy, had induced him to take his steamer past Samburan wharf (at an average distance of a mile) every twenty-three days--exactly. Davidson was delicate, humane, and regular. 

"Heyst called you in?" I asked, interested. 

Yes, Heyst had called him in as he was going by on his usual date. Davidson was examining the shore through his glasses with his unwearied and punctual humanity as he steamed past Samburan. 

I saw a man in white. It could only have been Heyst. He had fastened some sort of enormous flag to a bamboo pole, and was waving it at the end of the old wharf. 

Davidson didn't like to take his steamer alongside--for fear of being indiscreet, I suppose; but he steered close inshore, stopped his engines, and lowered a boat. He went himself in that boat, which was manned, of course, by his Malay seamen.  (End of story)
