But Dr. Knox, shortly repeating that he had no money to give her, made his escape. He had been ruffled enough already. One thing was certain: that if some beneficent sprite from fairyland increased Mrs. Knox’s annual income cent. per cent. she would still, and ever, be in embarrassment. Arnold knew this.

Mrs. Knox sat on, revolving difficulties. How many similar interviews she had held with her step-son, and how often he had been brought round to pay her bills, she could but remember. Would he do it now? A most unpleasant doubt, that he would not, lay upon her.

Presently the entrance was darkened by some tall form interposing itself between herself and the sunlight. She glanced up and saw Captain Collinson. He stood there smiling, his tasselled cane jauntily swayed in his left hand.

“My dear madam, you looked troubled. Is anything wrong?”

“Troubled! the world’s full of trouble, I think,” spoke Mrs. Knox, in a pettish kind of way. “Dr. Knox has been here to vex me.”

Captain Collinson stepped airily in, and sat down near Mrs. Knox, his eyes expressing proper concern: indignation blended with sympathy.

“Very inconsiderate of Dr. Knox: very wrong! Can I help you in any way, my dear lady?”

“Arnold is always inconsiderate. First, he begins upon me about Dicky, threatening to put him altogether away at school, poor ill-used child! Next, he——”

“Sweet little angel?” interlarded the captain.

“Next, he refuses to lend me a trifling sum of money—and he knows how badly I want it!”
