The author’s labours were cut short by the sudden intrusion of a maidservant.

“A gentleman to see you, sir,” said the maid, handing a card with the name Caiaphas Dwelf inscribed on it; “says it’s important.”

Mellowkent hesitated and yielded; the importance of the visitor’s mission was probably illusory, but he had never met any one with the name Caiaphas before. It would be at least a new experience.

Mr. Dwelf was a man of indefinite age; his high, narrow forehead, cold grey eyes, and determined manner bespoke an unflinching purpose. He had a large book under his arm, and there seemed every probability that he had left a package of similar volumes in the hall. He took a seat before it had been offered him, placed the book on the table, and began to address Mellowkent in the manner of an “open letter.”

“You are a literary man, the author of several well-known books—”

“I am engaged on a book at the present moment—rather busily engaged,” said Mellowkent, pointedly.

“Exactly,” said the intruder; “time with you is a commodity of considerable importance. Minutes, even, have their value.”

“They have,” agreed Mellowkent, looking at his watch.

“That,” said Caiaphas, “is why this book that I am introducing to your notice is not a book that you can afford to be without. Right Here is indispensable for the writing man; it is no ordinary encyclopædia, or I should not trouble to show it to you. It is an inexhaustible mine of concise information—”

“On a shelf at my elbow,” said the author, “I have a row of reference books that supply me with all the information I am likely to require.”
