Juve got up. It was little in accord with his active temperament to sit still. Once more he went all round the flat.
"The kitchen? Let me see: I have been through everything? The stove? The cupboards? The saucepans? Why, I went so far as to make sure that there was no poison in them, though it seemed a wild idea. The anteroom? Nothing there: the umbrella stand was empty, and the one interesting thing I did see, the torn curtain, has been described and photographed officially." He went back into the dining-room. "I've searched all the furniture: and I went through all the parcels Gurn had done up before he left, and would, no doubt, have come back for at his leisure, had it not been for my discovery of the body, and the unfortunate publicity the newspapers gave to that fact." In one corner of the room was a heap of old newspapers, crumpled and torn, and thrown down in disorder. Juve kicked them aside. "I've looked through all that, even read the agony columns, but there was nothing there." He went into the bedroom and contemplated the bed, that the concierge had stripped, the chairs set one on top of another in a corner, and the wardrobe that stood empty, its former contents scattered on the floor by the police during their search. There, too, nothing was to be found.
Against the wall, near the fireplace, was a little escritoire with a cupboard above it, containing a few battered books.
"My men have been all through that," Juve muttered; "it's most unlikely that they missed anything, but perhaps I had better see."
He sat down before it and began methodically to sort the scattered papers; with quick, trained glance he scanned each document, putting one after another aside with a grimace expressive of disappointment. Almost the last document he picked up was a long sheet of parchment, and as he unfolded it an exclamation escaped his lips. It was an official notice of Gurn's promotion to the rank of sergeant when fighting under Lord Beltham in the South African War. Juve read it through — he knew English well — and laid it down with a gesture of discouragement.
"It is extraordinary," he muttered. "That seems to be perfectly authentic; it is authentic, and it proves that this fellow was a decent fellow and a brave soldier once; that is a fine record of service." He drummed his fingers on the desk and spoke aloud. "Is Gurn really Gurn, then, and have I been mistaken from start to finish in the little romance I have been weaving round him? How am I to find the key to the mystery? How am I to prove the truth of what I feel to be so very close to me, but which eludes me every time, just as I seem to be about to grasp it?"
He went on with his search, and then, looking at the bookcase, took the volumes out and, holding each by its two covers, shook it to make sure that no papers were hidden among the leaves. But all in vain. He did the same with a large railway time-table and several shipping calendars.
"The odd thing is," he thought, "that all these time-tables go to prove that Gurn really was the commercial traveller he professed to be. It's exactly things such as these one would expect to find in the possession of a man who travelled much, and always had to be referring to the dates of sailing to distant parts of the world."
In the bookcase was a box, made to represent a bound book, and containing a collection of ordnance maps. Juve took them out to make sure that no loose papers were included among them, and one by one unfolded every map.
Then a sharp exclamation burst from his lips.
"Good Lord! Now there —— "
In his surprise he sprang up so abruptly that he pushed back his chair, and overturned it. His excitement was so great that his hands were shaking as he carefully spread out upon the desk one of the ordnance maps he had taken from the case.
"It's the map of the centre district all right: the map which shows Cahors, and Brives, and Saint-Jaury and — Beaulieu! And the missing piece — it is the missing piece that would give that precise district!"
Juve stared at the map with hypnotised gaze; for a piece had been cut out of it, cut out with a penknife neatly and carefully, and that piece must have shown the exact district where the château stood which had been occupied by the Marquise de Langrune.
"Oh, if I could only prove it: prove that the piece missing from this map, this map belonging to Gurn, is really and truly the piece I found near Verrières Station just after the murder of the Marquise de Langrune — what a triumph that would be! What a damning proof! What astounding consequences this discovery of mine might have!"
Juve made a careful note of the number of the map, quickly and nervously, folded it up again, and prepared to leave the flat.
He had made but a step or two towards the door when a sharp ring at the bell made him jump.
"The deuce!" he exclaimed softly; "who can be coming to ring Gurn up when everybody in Paris knows he has been arrested?" and he felt mechanically in his pocket to make sure that his revolver was there. Then he smiled. "What a fool I am! Of course it is only Mme. Doulenques, wondering why I am staying here so long."
He strode to the door, flung it wide open, and then recoiled in astonishment.
"You?" he exclaimed, surveying the caller from top to toe. "You? Charles Rambert! Or, I should say, Jérôme Fandor! Now what the deuce does this mean?"
XXIII
The Wreck of the "Lancaster"
Jérôme Fandor entered the room without a word. Juve closed the door behind him. The boy was very pale and manifestly much upset.
"What is the matter?" said Juve.
"Something terrible has happened," the boy answered. "I have just heard awful news: my poor father is dead!"
"What?" Juve exclaimed sharply. "M. Etienne Rambert dead?"
Jérôme Fandor put a newspaper into the detective's hand. "Read that," he said, and pointed to an article on the front page with a huge head-line: "Wreck of the 'Lancaster': 150 Lives Lost." There were tears in his eyes, and he had such obvious difficulty in restraining his grief, that Juve saw that to read the article would be the speediest way to find out what had occurred.
The Red Star liner Lancaster, plying between Caracas and Southampton, had gone down with all hands the night before, just off the Isle of Wight, and at the moment of going to press only one person was known to have been saved. There was a good sea running, but it was by no means rough, and the vessel was still within sight of the lighthouse and making for the open sea at full speed, when the lighthousemen suddenly saw her literally blown into the air and then disappear beneath the waves. The alarm was given immediately and boats of all kinds put off to the scene of the disaster, but though a great deal of wreckage was still floating about, only one man of the crew was seen, clinging to a spar; he was picked up by the Campbell and taken to hospital, where he was interviewed by The Times, without, however, being able to throw any light upon what was an almost unprecedented catastrophe in the history of the sea. All he could say was that the liner had just got up full speed and was making a perfectly normal beginning of her trip, when suddenly a tremendous explosion occurred. He himself was engaged at the moment fastening the tarpaulins over the baggage hold, and he was confident that the explosion occurred among the cargo. But he could give absolutely no more information: the entire ship seemed to be riven asunder, and he was thrown into the sea, stunned, and knew no more until he recovered consciousness and found himself aboard the Campbell.
