“You don’t seem to understand,” said Captain Heron wearily. “You expect me to make Rule believe I’ve urgent business to discuss with him—”

The Viscount interposed. “It’s you who don’t understand,” he said. “All we care about is keeping Rule away from Vauxhall tonight. If we don’t do it the game’s up. It don’t matter a ha’porth how you keep him away so long as you do keep him away.”

Captain Heron hesitated. “I know that. I’d do it if only I could think of anything reasonable to discuss with him.”

“You’ll think of it, never fear,” said the Viscount encouragingly. “Why, you’ve got the whole afternoon before you. Now you go round to Grosvenor Square at once, there’s a good fellow.”

“I wish to God I’d put off my visit to town till next week!” groaned Captain Heron, reluctantly picking up his hat again.

The Earl of Rule was just about to go in to luncheon when his second visitor was announced. “Captain Heron?” he said. “Oh, by all means show him in!” He waited, standing before the empty fireplace until the Captain came in. “Well, Heron?” he said, holding out his hand. “You come just in time to bear me company over luncheon.”

Captain Heron blushed in spite of himself. “I’m afraid I can’t stay, sir. I’m due in Whitehall almost immediately. I came—you know my time is limited—I came to ask you whether it would be convenient—in short, whether I might wait on you this evening for—for a talk of a confidential nature.”

The Earl’s amused glance rested on him thoughtfully. “I suppose it must be tonight?” he said.

“Well, sir—if you could arrange—I hardly know how I may manage tomorrow,” said Captain Heron, acutely uncomfortable.

There was a slight pause. “Then naturally I am quite at your service,” replied his lordship.
