So, before they could move further against Mr. Caryll, it behooved them to ascertain precisely to what extent Lord Ostermore might not be incriminated, as otherwise the arrest of Caryll might lead to exposures that would ruin the earl more thoroughly than could any South Sea bubble revelations. Thus her ladyship to her son. He turned upon her. “Why, madam,” said he, “these be the very arguments I used t'other day when we talked of this; and all you answered me then was to call me a dull-witted clod, for not seeing how the thing might be done without involving my lord.” “Tcha!” snapped her ladyship, beating her knuckles impatiently with her fan. “A dull-witted clod did I call you? 'Twas flattery--sheer flattery; for I think ye're something worse. Fool, can ye not see the difference that lies betwixt your disclosing a plot to the secretary of state, and causing this Caryll to disclose it--as might happen if he were seized? First discover the plot--find out in what it may consist, and then go to Lord Carteret to make your terms.” He looked at her, out of temper by her rebuke. “I may be as dull as your ladyship says--but I do not see in what the position now is different from what it was.” “It isn't different--but we thought it was different,” she explained impatiently. “We assumed that your father would not have betrayed himself, counting upon his characteristic caution. But it seems we are mistook. He has betrayed himself to Caryll. And before we can move in this matter, we must have proofs of a plot to lay before the secretary of state.” Lord Rotherby understood, and accounted himself between Scylla and Charybdis, and when that evening Green's messenger found him, he gnashed his teeth in rage at having to allow this chance to pass, at being forced to temporize until he should be less parlously situated. He returned Mr. Green an urgent message to take no steps concerning Mr. Caryll until they should have concerted together. Mr. Green was relieved. Mr. Caryll arrested might stir up matters against the slayer of Sir Richard, and this was a business which Mr. Green had prevision enough to see his master, Lord Carteret, would prefer should not be stirred up. He had a notion, for the rest, that if Mr. Caryll were left to go his ways, he would not be likely to give trouble touching that same matter. And he was right in this. Before his overwhelming sense of loss, Mr. Caryll had few thoughts to bestow upon the manner in which that loss had been sustained. Moreover, if he had a quarrel with any one on that account, it was with the government whose representative had issued the warrant for Sir Richard's arrest, and no more with the wretched tipstaff who had fired the pistol than with the pistol itself. Both alike were but instruments, of slightly different degrees of insensibility.
