"I’ll tell you my reason. I don’t know where I am, but we had better camp here till morning, and then explore. Keep a look-out while I glance over the engine; we must be ready to get off again at a moment’s notice." He switched on the light and made a careful examination of the engine; then, rubbing his dirty hands on the grass, he threw himself down beside his companion. "We’ve had uncommon luck," he said. "You under-estimate the personal equation," returned the other. "I consider myself supremely lucky in having met you. Your daring is as great as your ingenuity, Amory. By the way, I have the advantage of you. I have as many names as the chameleon has colours, but the names given me in baptism were Lewis Granger. Now we’re quits on that score." "Thanks. You are a spy, I suppose?" "Well, that rather opprobrious term would cover me, I presume. A sensitive person might prefer to call himself a secret agent. What’s in a name?" "It’s pretty dangerous work, anyhow, and I’m jolly glad you’re out of the Germans’ clutches. You asked why I came down. It’s because I’m a sort of secret agent too." "You don’t say so!" "Oh, it’s quite involuntary. I happened to overhear a conversation a few hours before I was nabbed. I’ll tell you about it." "Wait. I have no credentials. Do you think it wise to confide in a stranger?" "That’s all right," said Kenneth, who had taken an instant liking to the man. "We’re in the same boat. What I overheard was a scheme for blowing up a bridge somewhere in Belgium, and I thought that before going on to England I might put the Belgians up to it." "That’s worth a few hours’ delay. What you say confirms my own knowledge of the extraordinary minuteness of the German plans. ’Somewhere in Belgium,’ you say. You don’t know where?" "No. The name of the river was not mentioned either by Hellwig or----" "Hellwig! Does his Christian name happen to be Kurt?" "Yes. Do you know him?" "I have crossed swords with him--not literally, you understand, though nothing would please me better than a bout with him with the buttons off. I have one or two scores to settle with him. His Christian name would be more truly descriptive with the loss of a T. But how in the world did you come across him? He’s not the kind of man I should expect to meet in your company." "He’s the cousin of my poor father’s partner, Max Finkelstein. Max gives him a salary; he doesn’t earn a penny of it, but Max is a kind-hearted beggar. He wouldn’t do it if he knew that Hellwig was a--secret agent." "Don’t mind my feelings, my dear fellow," said Granger, with a laugh. "We’re a very mixed lot, I assure you. Do you mind repeating what you overheard, as nearly as you can remember it?" When the story was told, Granger acknowledged that ignorance of the position of the bridge was an obstacle to forewarning the Belgian authorities.
