"Well," he said, surveying Desmond, "and how do we find ourselves to-day? These chills are nasty things to shake off, my dear sir!"

"Oh, stow that!" growled Desmond, who was in little mood for joking.

"Voice inclined to be laryngeal," said Crook putting down his hat and bag on a chair, "we shall have to take care of our bronchial tubes! We are not so young as we were!"

"You can drop all that mumming, Crook!" snapped Desmond irascibly.

"Voice rotten," replied Crook calmly surveying him through his pince-nez. "Really, Major--I should say, Mr. Bellward--you must take more pains than that. You are talking to me exactly as though I were a British Tommy. Tut, tut, this will never do, sir!

You must talk thicker, more guttural-like, and open the vowels well."

He had dropped his jesting manner altogether and spoke with the deep earnestness of the expert airing his pet topic. He was so serious that Desmond burst out laughing. It must be said, however, that he laughed as much like a German as he knew how.

This appeared to mollify Crook who, nevertheless, read him a long lecture against ever, for a moment, even when alone, quitting the role he was playing. Desmond took it in good part; for he knew the soundness of the other's advice.

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 communiques 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 a.s.sured him that, by about the end of the week, the tow subst.i.tute, 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 Ess.e.x. 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.

He was surprised to find how remote the Mill House lay from other habitations. Between it and Wentfield station, once Wentfield village was pa.s.sed, there were only a few lonely farms; but to the south there was an absolutely uninhabited tract of fen traversed by the road running past the front gate of the Mill House. The Mill House was duly marked on the map; with a little blue line showing the millrace which Desmond traced to its junction with one of the broad d.y.k.es intersecting Morstead Fen.

The only inhabited house to the south of the Bellward villa appeared to be a lonely public house situated on the far edge of the fen, a couple of hundred yards away from the road. It was called "The d.y.k.e Inn."

One afternoon--it was the fifth day after Desmond's arrival at Bellward's--Mr. Crook announced that this was to be his last visit.

"I go abroad to-night, Mr. Bellward," he said (he always insisted on addressing Desmond by his a.s.sumed name), "a little job o' work in Switzerland; at Berne, to be precise. Urgent, you might call it, and really, sir, you've made so much progress that I think I can safely leave you. And I was to say that you will be able to go out very soon now."

"Good!" exclaimed Desmond, rubbing his hands together. "And you think I'll do, Crook, eh?"

Crook rubbed his nose meditatively.

"I'll be quite frank with you, Mr. Bellward," he said: "With a superficial acquaintance, even with an intimate friend, if he's as un.o.bservant as most people are, you'll pa.s.s muster. But I shouldn't like to guarantee anything if you were to meet, say, Mrs. Bellward, if the gentleman has got a wife, or his mother.

Keep out of a strong light; don't show your profile more than you can help, and remember that a woman is a heap more observant than a man.

"That's my advice to you, sir. And now I'll take my leave! You won't want that tow beard any more after to-day."

That night Desmond slept well and did not awake until the sunshine was streaming in between the Venetian blinds in his bedroom. He felt keen and vigorous, and he had an odd feeling that something was going to happen to him that day.

It was a delicious morning, the air as balmy as spring. As he brushed his hair in front of the window, Desmond saw the peewits running about in the sunshine on the fields by the road. He made an excellent breakfast and then, lighting a pipe, opened the Times which lay folded by his plate.

He turned first, as was his daily habit, to the casualty list.

There it was! Under the names of the "Killed in Action," he read: "Okewood, Major D. J. P.," followed by the name of his regiment.

It gave him an odd little shock, though he had looked for the announcement every day; but the feeling of surprise was quickly followed by one of relief. That brief line in the casualty list meant the severing of all the old ties until he had hunted down his quarry.

Now he was ready to start.

He spent the morning in the garden. Here, for the first time, he met Mr. Hill, the odd man, who, on seeing him, became intensely busy picking up handfuls of leaves and conveying them to a fire which was smouldering in a corner. Desmond essayed to enter into conversation with him but the man was so impenetrably deaf that Desmond, tiring of bawling, "It's a fine day!" in Mr. Hill's ear, left him and strolled over to the shed where the motor-cycle was stored. Here he amused himself for more than an hour in taking the machine to pieces and putting it together again. He satisfied himself that the bike was in working order and filled up the tank. He had an idea that this means of conveyance might come in useful.

The day was so mild that he lunched by the open window with the sunshine casting rainbows on the tablecloth through the wine-gla.s.ses. He was just finishing his coffee when the housekeeper came in and told him he was wanted on the telephone.

Desmond sprang from his chair with alacrity. His marching orders at last! he thought, as he hurried across the hall to the library.

"Hullo!" he cried as he picked up the receiver.

"Is that Mr. Bellward?" answered a nasal voice.

"Bellward speaking!" said Desmond, wondering who had called him up. The voice was a man's but it was not the abrupt clear tones of the Chief nor yet Mr. Matthews' careful accents.

"Madame Le Bon wishes to see you!"

Madame Le Bon? thought Desmond. Why, that was the name that Nur-el-Din had given him. "I am Madame Le Bon, a Belgian refugee," she had said.

"Do you know whom I mean?" the voice continued.

"Certainly," replied Desmond. "You will come alone. Otherwise, Madame will not see you. You understand? If you do not come alone, you will waste your time!"

"Where are you speaking from?" Desmond asked.

"If you will turn to the left on leaving your front gate," the voice resumed, "and follow the road, a messenger will meet you and take you to the lady."

"But..." Desmond began.

"Will you come at once? And alone?" the nasal voice broke in sharply.

Desmond took a moment's thought. To go was to disobey orders; not to go was to risk losing a second chance of meeting Nur-el-Din.

To telephone to 700 Stanning for a.s.sistance would bring a hornets' nest about his ears; yet he might only see the dancer if he went alone. He lost no time in making up his mind. The Chief must allow him lat.i.tude for meeting emergencies of this kind. He would go.

"I will come at once," said Desmond.

"Good," said the voice and the communication ceased.

Somewhere aloft there sits a sweet little cherub whose especial job is to look after the headstrong. It was doubtless this emissary of providence that leant down from his celestial seat and whispered in Desmond's ear that it would be delightful to walk out across the fen on this sunny afternoon. Desmond was in the act of debating whether he would not take the motor-bike, but the cherub's winning way clinched it and he plumped for walking.
