of watching the old man, Mr. Vidal," said the short, keen-eyed naval man, turning to me with his hands in the pockets of his pea-jacket, "and he was a funny 'un. He often went out from Beacon House at one and two in the morning, and took long strolls towards Rimton and Overstrand. But Mrs. Dean never knew as he wasn't indoors, for I gather he used to let himself out very quietly. We often used to meet him a-creepin' about of a night. I can't think what he went out for, but I suppose he was a little bit eccentric, eh? Why," went on the coast-guard officer, "he'd often come into the station early of a mornin', and have a chat with me, and look through the big telescope. He used, sometimes, to stand a-gazin' out at the sea, a-gazin' at nothing, for half an hour on end – lost in thought like. I wonder what he fancied he saw there?"
"Yes," I said. "He was eccentric, like many rich men."
"Well, one night, not long ago," Day went on, "there were some destroyers a-passin' about midnight, and we'd been taking in their signals by flash-light, when, in the middle of it, who should come into the enclosure but old Mr. Gregory. He stood a-watchin' us for ten minutes or so. Then, all at once he says, 'I see they're signalling to the Hermes at Harwich.' This remark gave me quite a start, for he'd evidently been a-readin' all we had taken in – and it was a confidential message, too."
"Then he could read the Morse code," I exclaimed.
"Read it? I should rather think he could!" was the coast-guard officer's reply. "And mark you, the Wolverene was a-flashin' very quick. It was as much as I could do to pick it up through the haze. After that, I confess I didn't like him hanging about here so much as he did. But after all, I'm sorry – very sorry – that the poor old gent is dead."
"Did you ever see him meet anybody on his nightly rambles?" I asked.
"Yes, once. I saw him about six weeks ago, about three o'clock one dark, and terrible wet, mornin', out on the cliff near Rimton Gap. As I passed by he was a-talkin' to a tall young man in a drab mackintosh. Talkin' excited, he was, and a-wavin' his arms wild-like towards the sea. The young man spotted me first, and said something, whereupon the old gent dropped his argument, and the two of 'em walked on quietly together. I passed them, believing that his companion was only one of them simple-like fools we get about here sometimes in the summer. But I'd never seen him in Cromer. He was a perfect stranger to me."
"That's the only time you've seen him with any companion on these secret night outings?" I asked.
"Yes. I don't remember ever having seen him in the night with anybody else."
"Not even with his nephew?"
"No, not even with Mr. Craig."
"When he dropped in to chat with you at the coastguard station, did he show any inquisitiveness?" I asked.
"Well, he wanted to know all about things, as most of 'em do," laughed Day. "Ours is a war-station, you know, and folk like to look at the inside, and the flash-lamp I invented."
"The old fellow struck you as a bit of a mystery, didn't he?" Frayne asked, in his pleasant Norfolk brogue.
"Well, yes, he did," replied the coast-guard officer. "I remember one night last March – the eleventh, I think it was – when our people at Weybourne detected some mysterious search-lights far out at sea and raised an alarm on the 'phone all along the coast. It was a very dirty night, but the whole lot of us, from Wells right away to Yarmouth, were at once on the look-out. We could see search-lights but could make nothing of the signals. That's what puzzled us so. I went out along the cliff, and up Rimton way, but could see nothing. Yet, on my way back, as I got near the town, I suddenly saw a stream of light – about like a search-light – coming from the sea-front here. It was a-flashin' some signal. I was a couple of miles from the town, and naturally concluded it was one of my men with the flash-lamp. As I passed Beacon House, however, I saw old Mr. Gregory a-leanin' over the railings, looking out to sea. It was then about two o'clock. I supposed he had seen the distant lights, and, passing a word with him, I went along to the station. To my surprise, I found that we'd not been signalling at all. Then I recollected old Mr. Gregory's curious interest in the lights, and I wondered. In fact, I've wondered ever since, whether that answering signal I saw did not come from one of the front windows of Beacon House? Perhaps he was practisin' Morse!"
"Strange, very strange!" Frayne remarked. "Didn't you discover what craft it was making the signals?"
"No, sir. They are a mystery to this day. We reported by wire to the Admiralty, of course, but we've never found out who it was a-signalling. It's a complete mystery – and it gave us a bit of an alarm at the time, I can tell you," he laughed. "There was a big Italian yacht, called the Carlo Alberta, reported next day from Hunstanton, and it may, of course, have been her. But I am not inclined to think so."
CHAPTER IV
OPENS SEVERAL QUESTIONS
Our next step in the inquiry was a domiciliary visit to Beacon House.
While the public, including Mr. Day, were expecting to see his nephew, we, of course, were hoping to find old Gregory.
In this we were disappointed. Already Treeton knew that both men were missing from their lodgings. Yet while the police were watching everywhere for the dandified young man from London, the queer, white-haired old Sheffield steel manufacturer had slipped through their fingers and vanished as though the earth had swallowed him up.
Mrs. Dean's house was a typical seaside lodging-house, plainly and comfortably furnished – a double-fronted house painted pale blue, with large airy rooms and bay windows, which, situated high up and on the very edge of the cliff, commanded extensive views up and down the coast.
The sitting-room occupied by uncle and nephew, proved to be a big apartment on the first-floor, to the left of the entrance. The houses in that row had a front door from the asphalt path along the edge of the cliff and also a back entrance abutting upon the narrow street which ran into the centre of the town. Therefore, the hall went from back to front, the staircase ascending in the centre.
The room in which I stood with the detectives, was large, with a cheerful lattice-work wall-paper, and substantial leather-covered furniture. In the window was placed a writing-table, and upon it a telescope mounted on a stand. A comfortable couch was placed against the wall, while before the fire-place were a couple of deep-seated easy chairs, and a large oval table in the centre.
Indeed, the room possessed an air of homely comfort, with an absence of the inartistic seldom found in seaside apartments. The windows were open and the light breeze from the sun-lit sea slowly fanned the lace curtains. On the writing-table lay a quantity of papers, mostly tradesmen's receipts – all of which the old gentleman carefully preserved – some newspapers, a tin of tobacco, and several pipes.
Beside the fire-place lay a pair of Egyptian slippers in crimson morocco, evidently the property of young Craig, while his straw hat and cane lay upon the couch, together with the fawn Burberry coat which had been one of the common objects in Cromer. Everywhere were signs of occupation. Indeed, the cushions in the easy chairs were crumpled just as if the two men had only a little while before arisen from them, while in the grate were a number of ends of those gold-tipped cigarettes without which Craig was never seen.
Upon a peg behind the door hung another old grey mackintosh belonging to old Gregory – an exact replica of which had been worn by the man who had so mysteriously met his death.
But where was old Gregory? Aye, that was the question.
With Mrs. Dean, a homely person with hair brushed tightly back, and her husband looking on, we began a thorough search of the room, as well as of the two bedrooms on the next floor. The sitting-room was investigated first of all, but in the writing-table we found nothing of interest. One of the drawers had been emptied and a mass of tinder in the grate told a significant tale.
Old Mr. Gregory had burned a lot of documents before disappearing.
Why? Were they incriminating?
Why, too, had he so suddenly disappeared? Surely he would not have done so without knowledge of his nephew's tragic death!
For a full half-hour we rummaged that room and all that was in it, but, alas, found nothing.
