s just three days after the Doctor and the Admiral had
congratulated each other upon the closer tie which was to unite their
two families, and to turn their friendship into something even dearer
and more intimate, that Miss Ida Walker received a letter which caused
her some surprise and considerable amusement. It was dated from next
door, and was handed in by the red-headed page after breakfast.

"Dear Miss Ida," began this curious document, and then relapsed suddenly
into the third person. "Mr. Charles Westmacott hopes that he may have
the extreme pleasure of a ride with Miss Ida Walker upon his tandem
tricycle. Mr. Charles Westmacott will bring it round in half an hour.
You in front. Yours very truly, Charles Westmacott." The whole was
written in a large, loose-jointed, and school-boyish hand, very thin on
the up strokes and thick on the down, as though care and pains had gone

dancing past in two long ranks on either side, until they had passed
round Croydon and were approaching Norwood once more from the further
side.

"Aren't you tired?" she asked, glancing over her shoulder and turning
towards him a little pink ear, a fluffy golden curl, and one blue eye
twinkling from the very corner of its lid.

"Not a bit. I am just getting my swing."

"Isn't it wonderful to be strong? You always remind me of a
steamengine."

"Why a steamengine?"

"Well, because it is so powerful, and reliable, and unreasoning. Well, I
didn't mean that last, you know, but--but--you know what I mean. What is
the matter with you?"

"Why?"

"Because you have something on your mind. You have not laughed once."

He broke into a gruesome laugh. "I
