"Mister Pett, siz Pett sent f'r me t' watch out so's n.o.body kidnapped her son."

"Oggie," explained Mrs. Pett. "Miss Trimble was guarding darling Oggie."

"Why?"

"To--to prevent him being kidnapped, Peter."

Mr. Pett glowered at the stout boy. Then his eye was attracted by the forlorn figure of Jerry Mitch.e.l.l. He started.

"Was this fellow kidnapping the boy?" he asked.

"Sure," said Miss Trimble. "Caught h'm with th' goods. He w's waiting outside there with a car. I held h'm and this other guy up w'th a gun and brought 'em back!"

"Jerry," said Mr. Pett, "it wasn't your fault that you didn't bring it off, and I'm going to treat you right. You'd have done it if n.o.body had b.u.t.ted in to stop you. You'll get the money to start that health-farm of yours all right. I'll see to that. Now you run off to bed. There's nothing to keep you here."

"Say!" cried Miss Trimble, outraged. "D'ya mean t' say y' aren't going t' pros'cute? Why, aren't I tell'ng y' I caught h'm kidnapping th' boy?"

"I told him to kidnap the boy!" snarled Mr. Pett.

"Peter!"

Mr. Pett looked like an under-sized lion as he faced his wife. He bristled. The recollection of all that he had suffered from Ogden came to strengthen his determination.

"I've tried for two years to get you to send that boy to a good boarding-school, and you wouldn't do it. I couldn't stand having him loafing around the house any longer, so I told Jerry Mitch.e.l.l to take him away to a friend of his who keeps a dogs' hospital on Long Island and to tell his friend to hold him there till he got some sense into him. Well, you've spoiled that for the moment with your detectives, but it still looks good to me. I'll give you a choice. You can either send that boy to a boarding-school next week, or he goes to Jerry Mitch.e.l.l's friend. I'm not going to have him in the house any longer, loafing in my chair and smoking my cigarettes. Which is it to be?"

"But, Peter!"

"Well?"

"If I send him to a school, he may be kidnapped."

"Kidnapping can't hurt him. It's what he needs. And, anyway, if he is I'll pay the bill and be glad to do it. Take him off to bed now. To-morrow you can start looking up schools. Great G.o.dfrey!"

He hopped to the writing-desk and glared disgustedly at the _debris_ on it. "Who's been making this mess on my desk? It's hard!

It's darned hard! The only room in the house that I ask to have for my own, where I can get a little peace, and I find it turned into a beer-garden, and coffee or some d.a.m.ned thing spilled all over my writing-desk!"

"That isn't coffee, Peter," said Mrs. Pett mildly. This cave-man whom she had married under the impression that he was a gentle domestic pet had taken all the spirit out of her. "It's Willie's explosive."

"Willie's explosive?"

"Lord Wisbeach--I mean the man who pretended to be Lord Wisbeach--dropped it there."

"Dropped it there? Well, why didn't it explode and blow the place to Hoboken, then?"

Mrs. Pett looked helplessly at Willie, who thrust his fingers into his mop of hair and rolled his eyes.

"There was fortunately some slight miscalculation in my formula, uncle Peter," he said. "I shall have to look into it to-morrow.

Whether the trinitrotoluol--"

Mr. Pett uttered a sharp howl. He beat the air with his clenched fists. He seemed to be having a brain-storm.

"Has this--this _fish_ been living on me all this time--have I been supporting this--this _buzzard_ in luxury all these years while he fooled about with an explosive that won't explode! He pointed an accusing finger at the inventor. Look into it tomorrow, will you?

Yes, you can look into it to-morrow after six o'clock! Until then you'll be working--for the first time in your life--working in my office, where you ought to have been all along." He surveyed the crowded room belligerently. "Now perhaps you will all go back to bed and let people get a little sleep. Go home!" he said to the detective.

Miss Trimble stood her ground. She watched Mrs. Pett pa.s.s away with Ogden, and Willie Partridge head a stampede of geniuses, but she declined to move.

"Y' gotta cut th' rough stuff, 'ster Pett," she said calmly. "I need my sleep, j'st 's much 's everyb'dy else, but I gotta stay here. There's a lady c'ming right up in a taxi fr'm th' As...o...b..lt to identify this gook. She's after'm f'r something."

"What! Skinner?"

"'s what he calls h'mself."

"What's he done?"

"I d'no. Th' lady'll tell us that."

There was a violent ringing at the front door bell.

"I guess that's her," said Miss Trimble. "Who's going to let 'r in? I can't go."

"I will," said Ann.

Mr. Pett regarded Mr. Crocker with affectionate encouragement.

"I don't know what you've done, Skinner," he said, "but I'll stand by you. You're the best fan I ever met, and if I can keep you out of the penitentiary, I will."

"It isn't the penitentiary!" said Mr. Crocker unhappily.

A tall, handsome, and determined-looking woman came into the room. She stood in the doorway, looking about her. Then her eyes rested on Mr. Crocker. For a moment she gazed incredulously at his discoloured face. She drew a little nearer, peering.

"D'yo 'dentify 'm, ma'am?" said Miss Trimble.

"Bingley!"

"Is 't th' guy y' wanted?"

"It's my husband!" said Mrs. Crocker.

"Y' can't arrest 'm f'r _that!_" said Miss Trimble disgustedly.

She thrust her revolver back into the hinterland of her costume.

"Guess I'll be beatin' it," she said with a sombre frown. She was plainly in no sunny mood. "'f all th' hunk jobs I was ever on, this is th' hunkest. I'm told off 't watch a gang of crooks, and after I've lost a night's sleep doing it, it turns out 't's a nice, jolly fam'ly party!" She jerked her thumb towards Jimmy.

"Say, this guy says he's that guy's son. I s'pose it's all right?"

"That is my step-son, James Crocker."

Ann uttered a little cry, but it was lost in Miss Trimble's stupendous snort. The detective turned to the window.
