was so strange and gruesome that its every detail remains imprinted upon my memory.

The building then was lighted by four barred windows set so high in the walls that no one could look in from the outside. Blazing sunlight poured in at the two southerly windows and drew a sharp black pattern of the bars across the paved floor. Kneeling beside a stretcher, fully in this path of light, so that he presented a curious striped appearance, was a man who presently proved to be the divisional surgeon, and two paces beyond stood a police inspector who was engaged at the moment of our entrance in making entries in his note-book.

On the stretcher, so covered up that only his face was visible, lay one whom at first I failed to recognize, for the horribly contorted features presented a kind of mottled green appearance utterly indescribable.

Stifling an exclamation of horror, I stared and stared at that ghastly face, then:

"My God!" I muttered. "Yes! it is Sir Marcus!"

The surgeon stood up and the inspector advanced to meet Gatton, but my horrified gaze had strayed from the stretcher to a badly damaged and splintered packing-case, which was the only other object in the otherwise empty shed. At this I stared as much aghast as I had stared at the dead man.

The iron bands were broken and twisted and the whole of one side lay in fragments on the floor; but upon a board which had formed part of the top I perceived the figure of a cat roughly traced in green paint.

Beyond any shadow of doubt this crate was the same which on the night before had lain in the garage of the Red House!

CHAPTER III
THE GREEN IMAGE

"YES," said Gatton, "I was speaking no more than the truth when I told them that you had special information which I hoped you would place at my disposal. Some of the particulars were given to me over the 'phone, you see, and I was glad to find you here when I arrived. I should have consulted you in any event, and principally about—that."

He pointed to an object which I held in my hand. It was a little green enamel image; the crouching figure of a woman having a cat's head, a piece of Egyptian workmanship probably of the fourth century B.C. Considered in conjunction with the figure painted upon the crate, the presence of this little image was so amazing a circumstance that from the moment when it had been placed in my hand I had stood staring at it almost dazedly.

The divisional surgeon had gone, and only the local officer remained with Gatton and myself in the building. Sir Marcus Coverly presented all the frightful appearance of one who has died by asphyxia, and although of course there would be an autopsy, little doubt existed respecting the mode of his death. The marks of violence found upon the body could be accounted for by the fact that the crate had fallen a distance of thirty feet into the hold, and the surgeon was convinced that the injuries to the body had all been received after death, death having taken place in his opinion fully twelve hours before.

"You see," said Gatton, "when the crate broke several things which presumably were in Sir Marcus' pockets were found lying loose amongst the wreckage. That cat-woman was one of them."

"Yet it may not have been in any of his pockets at all," said I.

"It may not," agreed Gatton. "But that it was somewhere in the crate is beyond dispute, I think. Besides this is more than a coincidence."

And he pointed to the painted cat upon the lid of the packing-case. I had already told him of the episode at the Red House on the previous night, and now:

"The fates are on our side," I said, "for at least we know where the crate was despatched from."

"Quite so," agreed Gatton. "We should have got that from the carter later, of course, but every minute saved in an affair such as this is worth considering. As a pressman you will probably disagree with me, but I propose to suppress these two pieces of evidence. Premature publication of clews too often handicaps us. Now, what is that figure exactly?"

"It is a votive offering of a kind used in Ancient Egypt by pilgrims to Bubastis. It is a genuine antique, and if you think the history of such relics is likely to assist the investigation I can give you some further particulars this evening if you have time to call at my place."

"I think," said Gatton, taking the figure from me and looking at it with a singular expression on his face, "that the history of the thing is very important. The fact that a rough reproduction of a somewhat similar figure is painted upon the case cannot possibly be a coincidence."

I stared at him silently for a moment, then:

"You mean that the crate was specially designed to contain the body?" I asked.

"I am certainly of that opinion," declared Inspector Heath, the local officer. "It is of just the right size and shape for the purpose."

Once more I began to examine the fragments stacked upon the floor, and then I looked again at the several objects which lay beside the crate. They were the personal belongings of the dead baronet and the police had carefully noted in which of his pockets each object had been found. He was in evening dress and a light top-coat had been packed into the crate beside him. In this had been found a cigar-case and a pair of gloves; a wallet containing £20 in Treasury notes and a number of cards and personal papers had fallen out of the crate together with the cat statuette. The face of his watch was broken. It had been in his waistcoat pocket but it still ticked steadily on where it lay there beside its dead owner. A gold-mounted malacca cane also figured amongst the relics of the gruesome crime; so that whatever had been the object of the murderer, that of robbery was out of the question.

"The next thing to do," said Gatton, "is to trace Sir Marcus's movements from the time that he left home last night to the time that he met his death. I am going out now to 'phone to the Yard. We ought to have succeeded in tracing the carter who brought the crate here before the evening. I personally shall proceed to Sir Marcus's rooms and then to this Red House around which it seems to me that the mystery centers."

He put the enamel figure into his pocket and taking up the broken board which bore the painted cat:

"You are carrying a top-coat," he said. "Hide this under it!"

He turned to Inspector Heath, nodding shortly.

"All right," he said, with a grim smile, "go out now and talk to the crowd!"

Having issued certain telephonic instructions touching the carter who had delivered the crate to the docks, and then imparting to the representatives of the press a guarded statement for publication, Inspector Gatton succeeded in wedging himself into my little two-seater and ere long we were lurching and bumping along the ill-paved East-end streets.

The late Sir Marcus's London address, which had been unknown to me, we had learned from his cards, and it was with the keenest anticipation of a notable discovery that I presently found myself with Gatton mounting the stairs to the chambers of the murdered baronet.

At the very moment of our arrival the door was opened and a man—quite obviously a constable in plain clothes—came out. Behind him I observed one whom I took to be the late Sir Marcus's servant, a pathetic and somewhat disheveled figure.

"Hello, Blythe!" said Gatton, "who instructed you to come here?"

"Sir Marcus's man—Morris—telephoned the Yard," was the reply, "as he couldn't understand what had become of his master and I was sent along to see him."

"Oh," said Gatton, "very good. Report to me in due course."

Blythe departed, and Gatton and I entered the hall. The man, Morris, closed the door, and led us into a small library. Beside the telephone stood a tray bearing decanter and glasses, and there was evidence that Morris had partaken of a hurried breakfast consisting only of
