And where was Edward Langdale all this time? On the day which saw Lord Montagu a prisoner in the Bastille, the poor lad had been just a month in the Chateau de Coiffy; and his captivity was not yet at an end. Care had been taken that he should have no opportunity of seeing Lord Montagu; and, though he was well treated, and his personal liberty seemed but little abridged within the walls, there was a cold, silent guard kept over him which tended a good deal to subdue his impatient spirit. If he spoke to any one, he received a civil answer; but it was confined to two or three words, and never afforded any information. If he asked for writing-materials, they were promised, but never came. If he walked on one of the ramparts, there was a soldier at each end, who never lost sight of him; and his own chamber, with one or two of the passages near, was the only place where he found himself free from supervision. His principal resort was the walls, where on fine days he would sit and think, and gaze over the undulating country round, for hours,--pondering his own fate, dreaming of Lucette, or asking himself what the conduct of Monsieur de Bourbonne could mean. It certainly had its meaning; and the secret was a very simple one. The reader has already the key in the few words spoken by the count on the first night of Edward's captivity. He had determined that the youth should have no communication with Richelieu till he himself had reaped the reward he expected for the valuable services he believed he had rendered.
