Sometimes Roger would take a stroll along Gissing Street before turning in. All day spent with books has a rather exhausting effect on the mind, and he used to enjoy the fresh air sweeping up the dark Brooklyn streets, meditating some thought that had sprung from his reading, while Bock sniffed and padded along in the manner of an elderly dog at night.

While Mrs. Mifflin was away, however, Roger's routine was somewhat different. After closing the shop he would return to his desk and with a furtive, shamefaced air take out from a bottom drawer an untidy folder of notes and manuscript. This was the skeleton in his closet, his secret sin. It was the scaffolding of his book, which he had been compiling for at least ten years, and to which he had tentatively assigned such different titles as "Notes on Literature," "The Muse on Crutches," "Books and I," and "What a Young Bookseller Ought to Know." It had begun long ago, in the days of his odyssey as a rural book huckster, under the title of "Literature Among the Farmers," but it had branched out until it began to appear that (in bulk at least) Ridpath would have to look to his linoleum laurels. The manuscript in its present state had neither beginning nor end, but it was growing strenuously in the middle, and hundreds of pages were covered with Roger's minute script. The chapter on "Ars Bibliopolae," or the art of bookselling, would be, he hoped, a classic among generations of book vendors still unborn. Seated at his disorderly desk, caressed by a counterpane of drifting tobacco haze, he would pore over the manuscript, crossing out, interpolating, re-arguing, and then referring to volumes on his shelves. Bock would snore under the chair, and soon Roger's brain would begin to waver. In the end he would fall asleep over his papers, wake with a cramp about two o'clock, and creak irritably to a lonely bed.

All this we mention only to explain how it was that Roger was dozing at his desk about midnight, the evening after the call paid by Aubrey Gilbert. He was awakened by a draught of chill air passing like a mountain brook over his bald pate. Stiffly he sat up and looked about. The shop was in darkness save for the bright electric over his head. Bock, of more regular habit than his master, had gone back to his couch in the kitchen, made of a packing case that had once coffined a set of the Encyclopaedia Britannica.

"That's funny," said Roger to himself. "Surely I locked the door?" He walked to the front of the shop, switching on the cluster of lights that hung from the ceiling. The door was ajar, but everything else seemed as usual. Bock, hearing his footsteps, came trotting out from the kitchen, his claws rattling on the bare wooden floor. He looked up with the patient inquiry of a dog accustomed to the eccentricities of his patron.

"I guess I'm getting absent-minded," said Roger. "I must have left the door open." He closed and locked it. Then he noticed that the terrier was sniffing in the History alcove, which was at the front of the shop on the left-hand side.

"What is it, old man?" said Roger. "Want something to read in bed?" He turned on the light in that alcove. Everything appeared normal. Then he noticed a book that projected an inch or so beyond the even line of bindings. It was a fad of Roger's to keep all his books in a flat row on the shelves, and almost every evening at closing time he used to run his palm along the backs of the volumes to level any irregularities left by careless browsers. He put out a hand to push the book into place. Then he stopped.

"Queer again," he thought. "Carlyle's Oliver Cromwell! I looked for that book last night and couldn't find it. When that professor fellow was here. Maybe I'm tired and can't see straight. I'll go to bed."

The next day was a date of some moment. Not only was it Thanksgiving Day, with the November meeting of the Corn Cob Club scheduled for that evening, but Mrs. Mifflin had promised to get home from Boston in time to bake a chocolate cake for the booksellers. It was said that some of the members of the club were faithful in attendance more by reason of Mrs. Mifflin's chocolate cake, and the cask of cider that her brother Andrew McGill sent down from the Sabine Farm every autumn, than on account of the bookish conversation.

Roger spent the morning in doing a little housecleaning, in preparation for his wife's return. He was a trifle abashed to find how many mingled crumbs and tobacco cinders had accumulated on the dining-room rug. He cooked himself a modest lunch of lamb chops and baked potatoes, and was pleased by an epigram concerning food that came into his mind. "It's not the food you dream about that matters," he said to himself; "it's the vittles that walk right in and become a member of the family." He felt that this needed a little polishing and rephrasing, but that there was a germ of wit in it. He had a habit of encountering ideas at his solitary meals.

After this, he was busy at the sink scrubbing the dishes, when he was surprised by feeling two very competent arms surround him, and a pink gingham apron was thrown over his head. "Mifflin," said his wife, "how many times have I told you to put on an apron when you wash up!"

They greeted each other with the hearty, affectionate simplicity of those congenially wedded in middle age. Helen Mifflin was a buxom, healthy creature, rich in good sense and good humour, well nourished both in mind and body. She kissed Roger's bald head, tied the apron around his shrimpish person, and sat down on a kitchen chair to watch him finish wiping the china. Her cheeks were cool and ruddy from the keen air, her face lit with the tranquil satisfaction of those who have sojourned in the comfortable city of Boston.

"Well, my dear," said Roger, "this makes it a real Thanksgiving. You look as plump and full of matter as The Home Book of Verse."

"I've had a stunning time," she said, patting Bock who stood at her knee, imbibing the familiar and mysterious fragrance by which dogs identify their human friends. "I haven't even heard of a book for three weeks. I did stop in at the Old Angle Book Shop yesterday, just to say hullo to Joe Jillings. He says all booksellers are crazy, but that you are the craziest of the lot. He wants to know if you're bankrupt yet."

Roger's slate-blue eyes twinkled. He hung up a cup in the china closet and lit his pipe before replying.

"What did you say?"

"I said that our shop was haunted, and mustn't be supposed to come under the usual conditions of the trade."

"Bully for you! And what did Joe say to that?"

"'Haunted by the nuts!'"

"Well," said Roger, "when literature goes bankrupt I'm willing to go with it. Not till then. But by the way, we're going to be haunted by a beauteous damsel pretty soon. You remember my telling you that Mr. Chapman wants to send his daughter to work in the shop? Well, here's a letter I had from him this morning."

He rummaged in his pocket, and produced the following, which Mrs. Mifflin read:

DEAR MR. MIFFLIN,

I am so delighted that you and Mrs. Mifflin are willing to try the experiment of taking my daughter as an apprentice. Titania is really a very charming girl, and if only we can get some of the "finishing school" nonsense out of her head she will make a fine woman. She has had (it was my fault, not hers) the disadvantage of being brought up, or rather brought down, by having every possible want and whim gratified. Out of kindness for herself and her future husband, if she should have one, I want her to learn a little about earning a living. She is nearly nineteen, and I told her if she would try the bookshop job for a while I would take her to Europe for a year afterward.

As I explained to you, I want her to think she is really earning her way. Of course I don't want the routine to be too hard for her, but I do want her to get some idea of what it means to face life on one's own. If you will pay her ten dollars a week as a beginner, and
