Tremayne shook himself mentally. "I think we had better deal with the matter of this dispatch that was tampered with at Penalva."

"So we will, to be sure. But it can wait a minute." Sir Terence pushed back his chair, and rose. He crossed slowly to his secretary's side.

"What's on your mind, Ned?" he asked with abrupt solicitude, and Ned could not suspect that it was the matter on Sir Terence's own mind that was urging him--but urging him hopefully.

Captain Tremayne looked up with a rueful smile. "I thought you boasted that you never forced a confidence." And then he looked away. "Sylvia Armytage tells me that she is thinking of returning to England."

For a moment the words seemed to Sir Terence a fresh irrelevance; another attempt to change the subject. Then quite suddenly a light broke upon his mind, shedding a relief so great and joyous that he sought to check it almost in fear.

"It is more than she has told me," he answered steadily. "But then, no doubt, you enjoy her confidence."

Tremayne flashed him a wry glance and looked away again.

"Alas!" he said, and fetched a sigh.

"And is Sylvia the temptation, Ned?"

Tremayne was silent for a while, little dreaming how Sir Terence hung upon his answer, how impatiently he awaited it.

"Of course," he said at last. "Isn't it obvious to any one?" And he grew rhapsodical: "How can a man be daily in her company without succ.u.mbing to her loveliness, to her matchless grace of body and of mind, without perceiving that she is incomparable, peerless, as much above other women as an angel perhaps might be above herself?"

Before his glum solemnity, and before something else that Tremayne could not suspect, Sir Terence exploded into laughter. Of the immense and joyous relief in it his secretary caught no hint; all he heard was its sheer amus.e.m.e.nt, and this galled and shamed him. For no man cares to be laughed at for such feelings as Tremayne had been led into betraying.

"You think it something to laugh at?" he said tartly.

"Laugh, is it?" spluttered Sir Terence. "G.o.d grant I don't burst a blood-vessel."

Tremayne reddened. "When you've indulged your humour, sir," he said stiffly, "perhaps you'll consider the matter of this dispatch."

But Sir Terence laughed more uproariously than ever. He came to stand beside Tremayne, and slapped him heartily on the shoulder.

"Ye'll kill me, Ned!" he protested. "For G.o.d's sake, not so glum. It's that makes ye ridiculous."

"I am sorry you find me ridiculous."

"Nay, then, it's glad ye ought to be. By my soul, if Sylvia tempts you, man, why the devil don't ye just succ.u.mb and have done with it? She's handsome enough and well set up with her air of an Amazon, and she rides uncommon straight, begad! Indeed it's a broth of a girl she is in the hunting-field, the ballroom, or at the breakfast-table, although riper acquaintance may discover her not to be quite all that you imagine her at present. Let your temptation lead you then, entirely, and good luck to you, my boy."

"Didn't I tell you, O'Moy," answered the captain, mollified a little by the sympathy and good feeling peeping through the adjutant's boisterousness, "that poverty is just h.e.l.l. It's my poverty that's in the way."

"And is that all? Then it's thankful you should be that Sylvia Armytage has got enough for two."

"That's just it."

"Just what?"

"The obstacle. I could marry a poor woman. But Sylvia--"

"Have you spoken to her?"

Tremayne was indignant. "How do you suppose I could?"

"It'll not have occurred to you that the lady may have feelings which having aroused you ought to be considering?"

A wry smile and a shake of the head was Tremayne's only answer; and then Carruthers came in fresh from Lisbon, where he had been upon business connected with the commissariat, and to Tremayne's relief the subject was perforce abandoned.

Yet he marvelled several times that day that the hilarity he should have awakened in Sir Terence continued to cling to the adjutant, and that despite the many vexatious matters claiming attention he should preserve an irrepressible and almost boyish gaiety.

Meanwhile, however, the coming of Carruthers had brought the adjutant a moment's seriousness, and he reverted to the business of Captain Garfield. When he had mentioned the missing note, Carruthers very properly became grave. He was a short, stiffly built man with a round, good-humoured, rather florid face.

"The matter must be probed at once, sir," he ventured. "We know that we move in a tangle of intrigues and espionage. But such a thing as this has never happened before. Have you anything to go upon?"

"Captain Stanhope gave us nothing," said the adjutant.

"It would be best perhaps to get Grant to look into it," said Tremayne.

"If he is still in Lisbon," said Sir Terence.

"I pa.s.sed him in the street an hour ago," replied Carruthers.

"Then by all means let a note be sent to him asking him if he will step up to Monsanto as soon as he conveniently can. You might see to it, Tremayne."

CHAPTER X. THE STIFLED QUARREL

It was noon of the next day before Colonel Grant came to the house at Monsanto from whose balcony floated the British flag, and before whose portals stood a sentry in the tall bearskin of the grenadiers.

He found the adjutant alone in his room, and apologised for the delay in responding to his invitation, pleading the urgency of other matters that he had in hand.

"A wise enactment this of Lord Wellington's," was his next comment. "I mean this prohibition of duelling. It may be resented by some of our young bloods as an unwarrantable interference with their privileges, but it will do a deal of good, and no one can deny that there is ample cause for the measure."

"It is on the subject of the cause that I'm wanting to consult you,"

said Sir Terence, offering his visitor a chair. "Have you been informed of the details? No? Let me give you them." And he related how the dispatch bore signs of having been tampered with, and how the only doc.u.ment of any real importance came to be missing from it.

Colonel Grant, sitting with his sabre across his knees, listened gravely and thoughtfully. In the end he shrugged his shoulders, the keen hawk face unmoved.

"The harm is done, and cannot very well be repaired. The information obtained, no doubt on behalf of Ma.s.sena, will by now be on its way to him. Let us be thankful that the matter is not more grave, and thankful, too, that you were able to supply a copy of Lord Liverpool's figures.

What do you want me to do?"

"Take steps to discover the spy whose existence is disclosed by this event."

Colquhoun Grant smiled. "That is precisely the matter which has brought me to Lisbon."

"How?" Sir Terence was amazed. "You knew?"

"Oh, not that this had happened. But that the spy--or rather a network of espionage--existed. We move here in a web of intrigue wrought by ill-will, self-interest, vindictiveness and every form of malice. Whilst the great bulk of the Portuguese people and their leaders are loyally co-operating with us, there is a strong party opposing us which would prefer even to see the French prevail. Of course you are aware of this.

The heart and brain of all this is--as I gather the Princ.i.p.al Souza.

Wellington has compelled his retirement from the Government. But if by doing so he has restricted the man's power for evil, he has certainly increased his will for evil and his activities.
