The question bulked larger as he considered it; for in life no trouble is surmounted but another appears to confront us; nor is the most perfect success of an imperfect world without its drawback. Now that he held the elixir his, now that in fancy he had it in his grasp, the problem of the mode and the quantity which had seemed trivial and negligible a few days or hours before, grew to formidable dimensions; nor could he of himself discover any solution of it. He had counted on finding with the potion some scrap of writing, some memorandum, some hieroglyphics at least, that, interpreted by such skill as he could command, would give him the clue he sought. But if there was nothing, as the girl asserted, not a line nor a sign, the matter could be resolved in one way only. He must resort to pressure. With the potion and the man in his possession, he must force the secret from Basterga; force it by threats or promises or aught that would weigh with a man who lay helpless and in a dungeon. It would not be difficult to get the truth in that way: not at all difficult. It seemed, indeed, as if Providence--and Fabri and Petitot and Baudichon--had arranged to put the man in his power _ad hoc_. He hugged this thought to him, and grew so enamoured of it that he wondered that he had not had the courage to seize Basterga in the beginning. He had allowed himself to be disturbed by phantoms; there lay the truth. He should have seen that the scholar dared not for his own sake destroy a thing so precious, a thing by which he might, at the worst, ransom his life. The Syndic wondered that he had not discerned that point before: and still in sanguine humour he retired to bed, and slept better than he had slept for weeks, ay, for months. The elixir was his, as good as his; if he did not presently have Messer Basterga by the nape he was much mistaken. He had had the scholar watched and knew whither he was gone and that he would not return before noon. At nine o'clock, therefore, the hour at which he had directed Claude to come to him at his house, he approached the Royaumes' door. Pluming himself on the stratagem by which twice in the twenty-four hours he had rid himself of an inconvenient witness, he opened the door boldly and entered. On the hearth, cap in hand, stood not Claude, but Louis. The lad wore the sneaking air as of one surprised in a shameful action, which such characters wear even when innocently employed. But his actions proved that he was not surprised. With finger on his lip, and eyes enjoining caution, he signed to the Syndic to be silent, and with head aside set the example of listening. The Syndic was not the man to suffer fools gladly, and he opened his mouth. He closed it--all but too late. All but too late, if--the thought sent cold shivers down his back--if Basterga had returned. With an air almost as furtive as that of the lad before him, he signed to him to approach.
