Jefferson was the son of a wealthy City man. He enjoyed a liberal allowance, golfed, motored, and ploughed the smooth waters of the Thames in a steam-launch. He did everything, in fact, which cost money. Golf is not a cheap game as played in clubs round London; motoring is not a poor man's hobby; a steam-launch is a fairly expensive toy. Football and cricket are trifles light as air--from an expenditure point of view--compared with the pastimes Mr Jefferson followed. Mr Jefferson might have played football and cricket, for he was only twenty-six, but he preferred pursuits which betokened him to be the possessor of a well-filled purse. When he referred to his recreations he endeavoured to make it clear to his listeners that he had been out in his own motor-car, and that he had not been churning the pleasant reaches of Henley and Maidenhead at the invitation of any whisky baronet or tea and coffee knight. He had been, if you please, in his own launch. An unkind City acquaintance of his had once wondered--audibly--why Jefferson didn't have the receipted bill for his launch pasted on the exterior of the craft, just under her name. This was unkind, but they say very unkind things about and to each other in the City. The Stock Exchange--of which the Messrs Jefferson, father and son, were both members--is as merciless in its chaff as a public school. Which, as my public school readers will agree, is speaking very highly of the Stock Exchange.

For the rest, Mr Jefferson could make himself exceedingly agreeable when he liked, and as he was good-looking, attentive, gentlemanly, and always well dressed, it was not surprising that he had managed to make an impression on Dora's girlish and inexperienced mind. To tell the truth, Mr Jefferson had come to the conclusion that Dora would be his for the asking, and, therefore, was not going to hurry himself over the matter. She was a charming girl--the most charming girl he had ever met--and he admired her immensely. Possibly he would have been deeply in love with her by this time had she not always received him with a smile of genuine welcome and accepted his invitations to go here and there, and see this and that, with unconcealed delight. After the drudgery of the post-office counter, and the doubtful joys offered by her home circle, Mr Jefferson's society came as a very pleasant relief to Dora. Whenever they went out together he spent his money handsomely and gave her of the best--and Dora was accordingly grateful and quite prepared to whisper a tender affirmative when Harold Jefferson asked her to be his wife.

So stood the matter when Jefferson drove her home--she had begged off from her work early, at his request--this September evening. So stood the matter when Dora entered the drawing-room and was introduced to "Dr Mortimer."

When Harold Jefferson, following Dora at a leisurely pace, heard Jim say that he had met Miss Maybury before, he pricked up his ears. And when, on entering the drawing-room, he saw who the gentleman was that had met Dora before, a vague but distinct feeling of annoyance came over him. He had met Jim in the inimical manner already described, and, as he turned over the pages of the magazine, made up his mind to take an early opportunity to inform Mrs Maybury of the part this new boarder--Jefferson presumed Jim was a new boarder--had lately played before a large and interested audience.

Presently Dora and Frank came downstairs. The former looked prettier than ever in a white dress--with a pearl necklace, a gift Of Mr Jefferson's, round her fair neck, and some other tiny shining ornament in her hair. Frank looked unusually clean and dapper in his best suit, Dora having tied a neat bow for him and generally supervised his toilet.

Dora seated herself on the arm of her father's chair, and stroked the thin hair on his head in the caressing way both pretty and plain daughters are often pleased to exhibit. Once only Dora stole a shy and somewhat apprehensive glance at Jim. She had recognised Jim's voice directly he spoke to Mr Jefferson at the Exhibition, and had turned her face away, as she did not desire Jim, on the strength of his introduction to her earlier in the day, to address her whilst he was in such a quarrelsome mood.

And now--here he was--this Mr (or Dr) Mortimer--under her own father's roof; and here, too, was Mr Jefferson, who had already expressed his feelings with regard to this Mr (or Dr) Mortimer. Under the peculiar circumstances, Dora had no desire to enter into conversation with Jim, and so took shelter--as girls so often, and so wisely, do--under the paternal wing.

Frank, however, had no reason to avoid Mr Mortimer. He rather admired him for the easy way he had picked up his portmanteau and shouldered it upstairs. A real boy admires a strong man, and Frank was a real boy enough--suffering, at present, from being too much at home--for his summer holidays were only just over. So he seated himself by Jim.

"I say, Dr Mortimer," he said at length, "would you mind telling me how tall you are?"

Jim was genially glad of somebody to talk to.
