reward?”

“Halves,” said Johnson promptly, “and a clout ’long-side your head if you was coming any of your nonsense over me.”

“It’s not nonsense,” said Gerald very impressively. “If you’ll let us in I’ll tell you all about it. And when you’ve caught the burglars and got the swagdm back you just give me a quiddn for luck. I won’t ask for more.”

“Come along in, then,” said Johnson, “if the young ladies’ll excuse the towel. But I bet you do want something more off of me. Else why not claim the reward yourself?”

“Great is the wisdom of Johnson—he speaks winged words.” The children were all in the cottage now, and the door was shut. “I want you never to let on who told you. Let them think it was your own unaided pluck and far-sightedness.”

“Sit you down,” said Johnson, “and if you’re kidding you’d best send the little gells home afore I begin on you.”

“I am not kidding,” replied Gerald loftily, “never less. And anyone but a policeman would see why I don’t want anyone to know it was me. I found it out at dead of night, in a place where I wasn’t supposed to be; and there’d be a beastly row if they found out at home about me being out nearly all night. Now do you see, my bright-eyed daisy?”

Johnson was now too interested, as Jimmy said afterwards, to mind what silly names he was called. He said he did see—and asked to see more.

“Well, don’t you ask any questions, then. I’ll tell you all it’s good for you to know. Last night about eleven I was at Yalding Towers. No—it doesn’t matter how I got there or what I got there for—and there was a window open and I got in, and there was a light. And it was in the strong-room, and there were three men, putting silver in a bag.”

“Was it you give the warning, and they sent for the police?” Johnson was leaning eagerly forward, a hand on each knee.

“Yes, that was me. You can let them think it was you, if you like. You were off duty, weren’t you?”

“I was,” said Johnson, “in the arms of Murphy—”do

“Well, the police didn’t come quick enough. But I was there—a lonely detective. And I followed them.”

“You did?”

“And I saw them hide the booty and I know the other stuff from Houghton’s Court’s in the same place, and I heard them arrange about when to take it away.”

“Come and show me where,” said Johnson, jumping up so quickly that his Windsor arm-chair fell over backwards, with a crack, on the red-brick floor.

“Not so,” said Gerald calmly; “if you go near the spot before the appointed time you’ll find the silver, but you’ll never catch the thieves.”

“You’re right there.” The policeman picked up his chair and sat down in it again. “Well?”

“Well, there’s to be a motor to meet them in the lane beyond the boat-house by Sadler’s Rents at one o’clock tonight. They’ll get the things out at half-past twelve and take them along in a boat. So now’s your chance to fill your pockets with chinkdp and cover yourself with honour and glory.”

“So help me!”—Johnson was pensive and doubtful still—“so help me! you couldn’t have made all this up out of your head.”

“Oh yes, I could. But I didn’t. Now look here. It’s the chance of your lifetime, Johnson! A quid for me, and a still tongue for you, and the job’s done. Do you agree?”

“Oh, I agree right enough,” said Johnson. “I agree. But if you’re coming any of your larks—”

“Can’t you see he isn’t?” Kathleen put in impatiently. “He’s not a liar—we none of us are.”

“If you’re not on, say so,” said Gerald, “and I’ll find another policeman with more sense.”

“I could split about you being out all night,” said Johnson.

“But you wouldn’t be so ungentlemanly,” said Mabel brightly. “Don’t you be so unbelieving, when we’re trying to do you a good turn.”

“If I were you,” Gerald advised, “I’d go to the place where the silver is, with two other men. You could make a nice little ambush in the wood-yard—it’s close there. And I’d have two or three more men up trees in the lane to wait for the motor-car.”

“You ought to have been in the force, you ought,” said Johnson admiringly; “but s’pose it was a hoax!”

“Well, then you’d have made an ass of yourself—I don’t suppose it ud be the first time,” said Jimmy.

“Are you on?” said Gerald in haste. “Hold your
