The good-looking Count talked earnestly for half an hour, acquainting them fully with the work of Yvette’s agents in the Galdavian capital, until Dick became amazed at the perfection of the organisation which the alert young French girl had so swiftly created.

“Ostrovitch’s Party,” Fédor concluded, “usually meet at the house of General Mestich, who, as you know, is the Commander of the Headquarter Troops in Langengrad. He is a wonderfully able man, but is a confirmed gambler and bon viveur, and is head over ears in debt. He plays at the Jockey Club each night. There can be no doubt whatever that he has been bought by Germany. His house in the Dalmatinska for a long time has been notorious for its rowdy parties, and as a result it is quite easy for the conspirators to meet there without attracting undue attention. I am certain the Government does not realise how far things have gone yet. There is not a scrap of direct evidence. Mestich is personally very popular, and would in any ordinary matter carry with him a big volume of public opinion. But he dare not, as yet, venture on any direct revolutionary action. His hope is to give his plot some semblance of a popular movement, and he is gradually winning important adherents. If he is given enough time I think he will succeed. But without Bausch and Horst—that is without Germany—the plot must go to pieces. They are finding the money, which is being spent like water.”

“This is certainly interesting,” Dick exclaimed. “What are your intentions?”

“Well, immediately opposite Mestich’s house is an old building which for many years has been used as a store. It belongs to a loyalist friend of ours, and I can use it as I like. From one of the upper windows it is possible to see right into Mestich’s little salon, where the meetings are held. We will meet there to-night. You must come separately to the alley at the back; we dare not enter by the front. There is a small doorway there, half overgrown by clematis and apparently never used. I will be inside waiting to open the door when you knock.”

For the rest of the day Dick and Yvette were careful to behave as ordinary tourists “doing the sights” of Langengrad, the Rathaus, the Museum, and the Opera House, and still buying piles of useless souvenirs. But they were soon to realise that a careful watch was kept on all strangers in Langengrad.

Just as they were finishing dinner that night they were approached by an officious little black-moustached man who sent a waiter to call them aside. When they were in a small smoking-room he made a courteous request for their papers. These were, of course, in order, and Dick had no misgivings on the point. But for some reason the shrewd, sallow-faced official seemed suspicious, and Dick noticed with anxiety that he spoke faultless French.

Would his own, he wondered, pass muster?

“Monsieur speaks French like an Englishman,” the police officer suddenly rapped out.

Luckily Dick was prepared.

“Yes,” he answered readily, “I was brought up in England. I was at school at Rugby. My friends in our French Air Force nicknamed me ‘The Englishman.’”
