was asking for information, but my companion could give him but very little.
"I am watching the railway-station, sir," said Treeton over the 'phone, "and I've sent word to all the fishermen in my district not to take out any strangers. I've also warned all the garages to let me know if any stranger hires a car. The party we fancy may be wanted won't be able to get away if he's still in the district."
"Which is not very likely," I murmured in a low voice so that my words should not be heard over the wire.
When the conversation over the phone was ended, I sat chatting with Treeton, until, some twenty minutes later, three men, bearing unmistakably the cut of police-officers in plain clothes, entered the station.
Two of them were tall, dark-haired young fellows, dressed in neat navy-blue serge and wearing bowler hats. The third man, Inspector Frayne, as I learnt afterwards, was in dark grey, with a soft grey felt hat with the brim turned down in front.
"Well Treeton," said the Inspector briskly, "what's all the fuss about down here?"
"A case – a very funny case. That's all," replied the local inspector. "I told you over the 'phone all I know about it."
Then followed a brief, low-pitched conversation between the two officers. I saw Frayne look over at me inquisitively, and caught a few snatches of Treeton's words to him. "Great personal friend of the Chief Constable… Yes, quite all right… Writes about crime… No, no, nothing to do with newspapers … amateur, of course … decent sort."
I gathered from this that there was going to be no difficulty about my joining the party of police investigators. I was right. In a few moments Treeton brought Inspector Frayne over to me and we were introduced. Then, after a few friendly words, we started for the scene of the startling discovery of the morning.
We slipped out of the station in pairs, so as to avoid attracting attention, which might have led to our being followed and hampered in our movements by a crowd of idle and curious inhabitants.
Proceeding by way of the path which wound round the back of the high-up coast-guard station and so up over the cliff, we soon came to the seat where the body of old Mr. Gregory had been found.
The seat, a green-painted one with a curved back, that had more than once afforded me a comfortable resting-place, was the first out of the town towards the links. It was situate a little way from the footpath amid the rough grass of the cliff-top. Around it the herbage never grew on account of the constant tread from the feet of many daily visitors, so that clear about it was a small patch of bare sand.
On the right, upon the next point of the cliff, was another similar seat, while on the left the path leading back to the town was railed off because it was dangerous to approach too near the crumbling edge.
At the seat stood a very tall, thin, fair-haired young constable who had, since the discovery of old Gregory's body, remained on duty at the spot to prevent any one approaching it. This was done by Treeton's orders, who hoped, and very logically, that if the sand about the seat was not disturbed some tell-tale mark or footprint might be found by the detectives that would give a clue to the person or persons who had visited the seat with old Gregory in the early hours of that fatal morning.
Near the constable were two men with cameras, and at a little distance a small knot of curious idlers, all that remained of the many inquisitive folks who were at first attracted to the spot, but who, finding nothing to satisfy their curiosity, had soon returned to the town.
The morning was bright and calm, the sunlight reflected from a glassy sea, upon the surface of which were a dozen or so fishing-boats lifting their crab-pots, for the crabs of Cromer are far-famed amongst epicures for their excellencies. It was a peaceful, happy scene, that none could have suspected was the setting of a ghastly tragedy.
On arrival, Inspector Frayne, tall, grey-haired, with aquiline, clean-shaven face, assumed an attitude of ubiquitous importance that amused me.
"The body was found lying face downwards six feet beyond the south end of the seat," Treeton explained. "You see this mark in the grass?"
Looking, we all saw distinctly the impression that marked the spot where the unfortunate man had lain.
"No doubt," said the detective inspector, "the old gentleman was sitting on the seat when he was attacked from behind by somebody who sneaked quietly across the footpath, and he fell sideways from the seat. Have you looked for footprints?"
"There are a number of them, as you see," was Treeton's reply. "Nothing has been disturbed. I left all to you."
Gazing around, I saw that there were many prints of soles and heels in the soft sand about the seat. Many people had evidently sat there on the previous day. In the sand, too, some one had traced with a stick, in sprawly capitals, the word "Alice."
Frayne and his two provincial assistants bent and closely examined the prints in question.
"Women's mostly, I should say," remarked the detective inspector after a pause. "That's plain from the French heels, flat golf-shoe soles, and narrow rubber-pads, that have left their marks behind them. Better take some casts of these, Phelps," he said, addressing the elder of his subordinates.
"Forgive me for making a remark," I ventured. "I'm not a detective, but it strikes me that if anybody did creep across the grass from the path, as the Inspector rightly suggested, to attack the old man, he, or she, may have left some prints in the rear there. In the front here the footprints we have been examining are obviously those of people who had been sitting upon the seat long prior to the arrival of the victim."
"I quite agree, Mr. Vidal," exclaimed Treeton, and at this I thought the expert from Norwich seemed somewhat annoyed. "Yes," continued the local inspector, "it's quite possible, as Mr. Frayne said, that somebody did creep across the grass behind the old man. But unfortunately, there have been dozens of people over that very same spot this morning."
"Hopeless then!" grunted Frayne. "Why on earth, Treeton, did you let them swarm over there?" he queried testily. "Their doing so has rendered our inquiry a hundred per cent. more difficult. In all such cases the public ought to be rigorously kept from the immediate neighbourhood of the crime."
"At least we can make a search," I suggested.
"My dear Mr. Vidal, what is the use if half Cromer has been up here prying about?" asked the detective impatiently. "No, those feminine footprints in front of the seat are much more likely to help us. There's bound to be a woman in such a case as this. My motto in regard to crime mysteries is, first find the woman, and the rest is easy. In every great problem the 'eternal feminine,' as you writers put it, is ever present. She is in this one somewhere, you may depend upon it."
I did not answer him, judging that he merely emitted these sentiments in order to impress his listening subordinates with a due sense of his superior knowledge. But the search went on.
From the footpath across the grass to the seat was about thirty feet, and over the whole area all of us made diligent investigation. In one of the patches where the sand was bare of herbage I found the print of a woman's shoe – a smart little shoe – size 3, I judged it to be. The sole was well shaped and pointed, the heel was of the latest fashionable model – rather American than French.
I at once pointed it out to Frayne, but though he had so strongly expressed the opinion that there was a woman in the case, he dismissed it with a glance.
"Some woman came here yesterday evening with her sweetheart, I suppose," he said with a laugh.
But to me that footprint was distinctly instructive, for among the many impressed on the sand before the seat, I had not detected one that bore any resemblance to it. The owner of that American shoe had walked from the path to the back of the seat, but had certainly not sat down there.
I carefully marked the spot, and telling an old fisherman of my acquaintance, who stood by, to allow no one to obliterate it, continued my investigations.
Three feet behind the seat, in the midst of the trodden grass, I came upon two hairpins lying close together. Picking them up, I found they were rather thick, crinkled in the middle, and both of the same pale bronze shade.
Was it possible there had
