and, to tell the truth, no more was I. The club house at Tampico was the starting-point of many memories, and I was feeling lazy. Chiefly they centred round Jim, and it wasn't until I heard his voice behind me cheerfully greeting the stranger that I realised I was holding the paper upside down.
"Why, it's MacGregor," I heard him say. "The last time I saw you was in Singapore. How are you, my dear fellow?"
"Jim Maitland, by all that's wonderful!" The stranger got up and seized Jim's hand, and just then Jim caught sight of me.
"Come over here, Dick," he cried. "This is Jock MacGregor, and a partially-demented Government pays him a salary for cruising up and down outlandish waters and seeing that no one has walked off with a lighthouse or two. If they only knew what he did with his salary when he gets ashore they'd halve it in the interests of public morals."
"Salary!" snorted MacGregor. "Call my beggarly pittance a salary! And now the blighters have put a survey job on to my shoulders as well. Think I haven't enough work to do, I suppose."
"But what brings you here, Jock?" asked Jim. "Tampico is a bit out of your beaten track, isn't it?"
MacGregor nodded abruptly and the frown appeared once more.
"The supply-boat for the lighthouse at Corn Reef goes from here," he said. "It starts tomorrow, and I'm going with it."
"Visit of inspection?" said Jim.
"Yes and no," returned the other. "In all probability I shall stay there for a week or so."
Jim raised his eyebrows.
"Since when has the great Pooh Bah stayed at particular lighthouses?" he inquired. "I thought you merely looked in to see that the occupant hadn't been frying sausages on the lamps, and then passed gracefully on."
Jock MacGregor grinned, and then grew serious again.
"That's why I said yes and no. This isn't an ordinary inspection." He hesitated a moment, and then leant forward in his chair. "Care to hear the story, Jim?"
"Get it right off your chest, Jock," he said, beckoning to the waiter for drinks.

"Well, if it won't bore you, I will," began MacGregor. "Only I'll have to go back a bit. When we last met, I had nothing to do with this area at all. Bill Lambert had it, and mine was farther north. I don't know if you ever met Bill, but he took to seeing things that weren't there, from the usual cause, and has recently gone on permanent sick leave. They said they'd send a successor, as they always do say, but so far there's been no sign of him. And until his arrival Mr. MacGregor was to carry on with both areas— and no increase of pay. Bless their hearts! However, I didn't mind, and to do them justice, in normal circumstances it would have made no odds to me. If you've twice the area to cover, you do half the number of inspections, and it comes to the same thing in the end. It's just a matter of form and routine as you can guess—in normal circumstances."
He emphasised the last three words, and Jim glanced at him.
"One gathers that Corn Reef is not quite normal?" he remarked.
"I'm coming to that," said MacGregor, putting down his glass. "I don't know whether you know the part or not—personally, I only know it from the map. Corn Reef sticks out from a smallish island, called Taba Island, which I believe is inhabited by a few natives. It stretches about half way across a deep-water channel towards the next of the group, which is uninhabited. Beyond that again come other small islands and reefs, and in fact the only method of navigating the belt is through the other half of the deep-water channel I have told you about—one half of which is blocked by Corn Reef.
"The lighthouse stands on the end of the reef, midway across the channel. At low water it can be reached from the island on foot; at high water the reef is covered. So much for the locality; now for the personal details. Six months ago, as I said, I took over from Bill Lambert. It was an informal sort of taking over, as he had delirium tremens pretty badly, and I got no information out of him. But it didn't worry me much, as I'd no idea then that there was anything peculiar in his area. And it wasn't till a month ago, when I received a communication from the keeper at Corn Reef lighthouse, that I began to look into things. His name is David Temple, and the communication was brief and to the point. It stated that his assistant, when attending to the bell, had fallen into the sea and been drowned, and could another be sent."
"Bell?" interrupted Jim. "I don't quite follow."
"Sorry," said MacGregor. "I forgot that point. Apparently at certain times you get a thick belt of fog across the reef and the channel, and stretching right along the belt of islands. Probably it's some form of heavy ground mist. When that comes down they have as a warning for ships a huge bell, which is tolled mechanically. It is built out on a sort of platform below the level of the light, and as far as I can make out from the plans, it seems a pretty antiquated sort of arrangement. However, there it is, and as long as it functions you won't get them to spend any money in having it replaced by anything more up-to-date.
"Well, when I got Temple's letter I began looking up the files. And to my amazement I found that about three months before Bill Lambert had gone a precisely similar letter had reached him. At first I thought that the second was merely a reminder, and that Bill had forgotten all about it. So I made inquiries, only to discover the somewhat sinister fact that it was far from a reminder. Bill had sent a man, and I was therefore confronted with the situation that within some nine months two men, when attending to the bell at Corn Reef lighthouse, had fallen into the sea and been drowned. Which seemed to show that there was something radically wrong with the bell arrangements generally: something "—and MacGregor paused— "something, Jim, which I utterly failed to get at from the plans. I'm not denying that the whole idea is antiquated; but, granting the plans and sections are correct, it is perfectly safe. And I could see no reason whatever—short of a desire to commit suicide—why two men should fall into the sea."
"And even granting that, why of necessity they should be drowned?" said Jim quietly.
MacGregor shrugged his shoulders.
"The place is alive with sharks, of course," he remarked. "But I've not quite finished yet. Another unpleasant fact was brought to my notice shortly after I received this letter from Temple. I ran into the skipper of some craft or other in the club at Singapore, and he was looking for Bill Lambert's blood. And when he heard I was doing Bill's job he turned his wrath on me. And his accusation amounted to this: that on the morning of February 24th he was on the bridge of his ship nosing her gently through a thick mist. Suddenly there came a bellow from the look-out man, and to his horror he saw looming out of the mist on the star-hoard side—Corn Reef lighthouse.
"'My God, man!' he said to me. 'I could have spat an orange pip at it, and hit it; I could almost have touched it with my hand. In thirty years I've never had such an escape. Another foot—another six inches— and we'd have been on that reef.'
"But wasn't the bell ringing? I demanded.
"'Not a sound!' he roared. 'Not a sound. You can hear that bell for fifteen miles—and there wasn't a sound. Only as I passed by— damn it, why, the platform on which the bell is built nearly grazed my wireless—I looked up. Man! I tell you the bell was ringing right enough—I could see it through the fog—but no sound came. Only above the beat of the engine, I thought I heard a steady thud, thud, thud in time with the beat of the bell. But maybe it was my imagination.'"

Jock MacGregor paused and drained his drink.
"So that is the rather peculiar situation I'm up against."
"And how do you propose to deal with it?" asked Jim.
"Temple asked for an assistant," said MacGregor briefly, "and he's going to have one. He's going to have me." He lit a cigarette, and leant back in his chair. "There's something wrong, Jim," he continued after a moment, "something very wrong out there. That merchant skipper was as hard-headed a customer as you could meet, and if he saw that bell moving—it was moving. Then why was there no sound? And then two men drowned in nine months! I guess I'm not going to send a third till
