Chauvelin no longer made any pretence to hold Armand by the arm.
By temperament as well as by profession a spy, there was one subject at least which he had mastered thoroughly: that was the study of human nature. Though occasionally an exceptionally complex mental organisation baffled him--as in the case of Sir Percy Blakeney--he prided himself, and justly, too, on reading natures like that of Armand St. Just as he would an open book.
The excitable disposition of the Latin races he knew out and out; he knew exactly how far a sentimental situation would lead a young Frenchman like Armand, who was by disposition chivalrous, and by temperament essentially passionate. Above all things, he knew when and how far he could trust a man to do either a sublime action or an essentially foolish one.
Therefore he walked along contentedly now, not even looking back to see whether St. Just was following him. He knew that he did.
His thoughts only dwelt on the young enthusiast--in his mind he called him the young fool--in order to weigh in the balance the mighty possibilities that would accrue from the present sequence of events. The fixed idea ever working in the man's scheming brain had already transformed a vague belief into a certainty.
That the Scarlet Pimpernel was in Paris at the present moment Chauvelin had now become convinced. How far he could turn the capture of Armand St. Just to the triumph of his own ends remained to be seen.
But this he did know: the Scarlet Pimpernel--the man whom he had learned to know, to dread, and even in a grudging manner to admire--was not like to leave one of his followers in the lurch.
Marguerite's brother in the Temple would be the surest decoy for the elusive meddler who still, and in spite of all care and precaution, continued to baffle the army of spies set upon his track.
Chauvelin could hear Armand's light, elastic footsteps resounding behind him on the flagstones. A world of intoxicating possibilities surged up before him. Ambition, which two successive dire failures had atrophied in his breast, once more rose up buoyant and hopeful. Once he had sworn to lay the Scarlet Pimpernel by the heels, and that oath was not yet wholly forgotten; it had lain dormant after the catastrophe of Boulogne, but with the sight of Armand St. Just it had re-awakened and confronted him again with the strength of a likely fulfilment.
The courtyard looked gloomy and deserted. The thin drizzle which still fell from a persistently leaden sky effectually held every outline of masonry, of column, or of gate hidden as beneath a shroud. The corridor which skirted it all round was ill-lighted save by an occasional oil-lamp fixed in the wall.
But Chauvelin knew his way well. Heron's lodgings gave on the second courtyard, the Square du Nazaret, and the way thither led past the main square tower, in the top floor of which the uncrowned King of France eked out his miserable existence as the plaything of a rough cobbler and his wife.
Just beneath its frowning bastions Chauvelin turned back towards Armand. He pointed with a careless hand up-wards to the central tower.
"We have got little Capet in there," he said dryly. "Your chivalrous Scarlet Pimpernel has not ventured in these precincts yet, you see."
Armand was silent. He had no difficulty in looking unconcerned; his thoughts were so full of Jeanne that he cared but little at this moment for any Bourbon king or for the destinies of France.
Now the two men reached the postern gate. A couple of sentinels were standing by, but the gate itself was open, and from within there came the sound of bustle and of noise, of a good deal of swearing, and also of loud laughter.
The guard-room gave on the left of the gate, and the laughter came from there. It was brilliantly lighted, and Armand, peering in, in the wake of Chauvelin, could see groups of soldiers sitting and standing about. There was a table in the centre of the room, and on it a number of jugs and pewter mugs, packets of cards, and overturned boxes of dice.
But the bustle did not come from the guard-room; it came from the landing and the stone stairs beyond.
