“I know wot I’m going to do without you telling me,” said Mr. Gibbs, nodding.  “I’ll bet you pots round that you don’t either of you reckernize me tomorrow night.”

The bet was taken at once, and from eight o’clock until ten minutes to nine the following night Messrs. Kidd and Brown did their best to win it.  Then did Mr. Kidd, turning to Mr. Brown in perplexity, inquire with many redundant words what it all meant.

[Illustration:  “Gone!” exclaimed both gentlemen.  “Where?”]

“He must ’ave gone on by ’imself,” said Mr. Brown.  “We’d better go and see.”

In a state of some disorder they hurried back to Wapping, and, mounting the stairs to Mrs. Gibbs’s room, found the door fast.  To their fervent and repeated knocking there was no answer.

“Ah, you won’t make her ’ear,” said a woman, thrusting an untidy head over the balusters on the next landing.  “She’s gone.”

“Gone!” exclaimed both gentlemen.  “Where?”

“Canada,” said the woman.  “She went off this morning.”

Mr. Kidd leaned up against the wall for support; Mr. Brown stood open-mouthed and voiceless.

“It was a surprise to me,” said the woman, “but she told me this morning she’s been getting ready on the quiet for the last fortnight.  Good spirits she was in, too; laughing like anything.”

“Laughing!” repeated Mr. Kidd, in a terrible voice.

The woman nodded.  “And when I spoke about it and reminded ’er that she ’ad only just lost ‘er pore husband, I thought she would ha’ burst,” she said, severely.  “She sat down on that stair and laughed till the tears ran dowwn ’er face like water.”

Mr. Brown turned a bewildered face upon his partner.  “Laughing!” he said, slowly.  “Wot ’ad she got to laugh at?”

“Two born-fools,” replied Mr. Kidd.
