This library, you felt, was seldom used. It had a correct air of weightiness: a claw-footed desk, a globe-map, and an overmantel of heavy carved wood. The books, clearly bought by the yard and unread, occupied two walls: in their contrasts of brown, red, blue, and black leather or cloth among the sets, even in an occasional artistic gap along the shelves, they showed the hand of the decorator. A bronze lamp burned on the desk.

"Now," Rich said through his teeth. "Please tell me the symptoms."

Courtney told him.

"And these symptoms came on when?"

"Just before tea-time, I understand."

"God in heaven!" muttered Rich, as though unable to believe his ears. He massaged his forehead, and then hastily consulted his watch. "Sixteen hours! Only sixteen hours! I can't believe it would have got as bad as that in only…"

His voice grew bewildered, almost piteous.

"I forget," he added. "I have not practiced medicine for eight years. Your knowledge grows scrambled. You…" His eyes wandered round the bookshelves. "I don't suppose they'd have any medical works here? Stop. There's a Britannica, at least. It might help to jog my memory."

The set of the Encyclopaedia Britannica, fourteenth edition, was on a rather high shelf. Rich stood on tiptoe and plucked down the twenty-first volume, "SORD to TEXT." He carried it to the desk under the lamp. His hands shook. But it was unnecessary for him to leaf through in order to find the article on tetanus.

An envelope, used as a book-mark, was already in the volume at the page containing the tetanus article.
