Then old Martha brought tea, and over the cups and saucers Crook gave Desmond a budget of news. He told of the warrant issued for the arrest of Nur-el-Din and of the search being made for her.

Desmond heard the news of Nur-el-Din’s disappearance from London with some consternation. He began to realize that his failure to detain Nur-el-Din that afternoon might have incalculable consequences. Sunk in thought, he let Crook run on. He was wondering whether he ought to give him a message for the Chief, telling him of Nur-el-Din’s visit and of her flight on the arrival of Mortimer.

Now, Desmond had a good deal of pride, and like most proud people, he was inclined to be obstinate. To confess to the Chief that he had let both Nur-el-Din and Mortimer slip through his fingers was more than he could face. He could not bear to think that the Chief might believe him capable of failure, and take independent measures to guard against possible mistakes. Also, in his heart of hearts, Desmond was angry with the Chief. He thought the latter had acted precipitately in getting out a warrant for Nur-el-Din’s arrest before he, Desmond, had had time to get into the skin of his part.

So Desmond heard Crook out and made no comment. When the other asked him if he had anything to tell the Chief, he shook his head. He was not to know then the consequences which his disobedience of orders was destined to have. If he had realized what the result of his obstinacy would be, he would not have hesitated to send a full report by Crook—and this story might never have been written!

But if youth followed reason instead of impulse, the world would stand still. Desmond was still at an age at which a man is willing to take on anything and anybody, and he was confident of bringing his mission to a successful conclusion without any extraneous aid. So Crook, after changing Desmond’s make-up and giving him a further rehearsal of his role, packed up his pots and paints and brushes in his black bag and returned to London with “nothing to report” as the communiqués say.

He repeated his visit every day for the next four days. Crook’s arrival each afternoon was the only break in the monotony of a life which was rapidly becoming unbearable to Desmond’s mercurial temperament. He found himself looking forward to the wizened little man’s visits and for want of better employment, he threw himself wholeheartedly into the study of his role under the expert’s able direction. Desmond’s beard had sprouted wonderfully, and Crook assured him that, by about the end of the week, the tow substitute, which Desmond found a most unmitigated nuisance, would be no longer necessary. He also showed his pupil how to paint in the few deft lines about the eyes which completed the resemblance between Bellward and his impersonator.

The time hung terribly heavily on Desmond’s hands. He had long since memorized and destroyed the list of Mr. Bellward’s friends. Every morning he spent at least an hour before the mirror in his bedroom working up the role. With every day he felt more confident of himself; with every day he grew more anxious to go to London, and, taking the bull by the horns, boldly visit one of Mr. Bellward’s acquaintances and test the effect of his disguise.

But no orders came from Headquarters to release him from his confinement. Moreover, no word arrived from Nur-el-Din nor did Mortimer send any message or call again at the Mill House. The silence of the two conspirators made Desmond uneasy. Suppose Mortimer, who, he felt sure, had caught him out lying about Nur-el-Din’s presence in the house at the time of his visit, had grown suspicious! What if Nur-el-Din had succeeded in making good her escape to the Continent? He had had his chance of laying hold of both suspects and he had failed. Would that chance come again?

Desmond doubted it. Every morning he awoke long before the dawn and lay awake until daylight, his mind racked by these apprehensions. He chafed bitterly at his inaction and he plied Crook with questions as to whether he had any orders for him. Each time Crook replied in the negative.

In the library Desmond found an Ordnance map of Essex. His military training had given him a good schooling in the use of maps, and he spent many hours studying the section of the country about the Mill House, seeking to impress it upon his mind against future emergencies.
