But his feeling was changed to the keenest anxiety when he found that the letter, though written more than a week after the date at which Grootz might reasonably be supposed to have received his letter, made no reference to the news he had sent, and had clearly been despatched in entire ignorance of the threatening danger. Long afterwards he learnt that the courier had been accidentally drowned in crossing a river at night, and his letters had been lost. He dreaded to think what might have happened in the interval. He wrote another urgent letter to Mynheer Grootz, and despatched it by a special messenger; but the bare possibility of a mishap alarmed him, and he could never put the subject from his thoughts. He woke at night under the pressure of his anxiety; if only he could himself go to Lindendaal to see that all was safe! But while the siege was still being prosecuted, and the prince had constant need of his services, he could not bring himself to ask for leave. His difficulty was solved for him by the prince himself. His evident preoccupation, and a slight mistake he made in noting down a message, attracted that astute gentleman’s attention. He spoke to Harry on the matter; by this time they were on such terms that Harry felt no difficulty in opening his mind; and he explained that having become aware of a plot likely to injure some friends of his, and fearing that his letter of warning had miscarried, he was in considerable anxiety on their behalf. "Naturally," said the prince. "Who are these friends of yours?" "A French refugee lady and her daughter, Monseigneur, who live near Breda." "Ah! What is their name?" "De Vaudrey, Monseigneur." "Are they relatives of yours?" "No, Monseigneur." "A mere matter of friendship, eh?" The prince’s eyes twinkled. "Now, my boy, confess: you are in love." "No, indeed, Monseigneur." "Well, the symptoms are not unusual. You ought to know best, of course; but in any case you had better get the matter off your mind. This weary siege cannot last more than a few days longer; we hear that the enemy are on the point of surrender; we shall go into winter quarters immediately, I suppose, and I shall be able to dispense with your services until the spring. Pack off to Breda and see your—friends, holding yourself in readiness, of course, to come back to me when summoned." Harry was too much pleased at the opportunity of assuring himself that all was well to think it necessary to make any protestation about his motives. Thanking the prince, he finished off one or two small duties and went to arrange with Sherebiah for their journey. Before he left he came across Fanshawe in camp, and, without disclosing his reasons, told him where he was going.
