"Miss Oman," I said. "I very much want to take your advice on a matter of some importance—to me, at least." (That ought to fetch her, I thought. The "advice fly"—strangely neglected by Izaak Walton—is guaranteed to kill in any weather.) And it did fetch her. She rose in a flash and gorged it, cock's feathers, worsted body and all.

"What is it about?" she asked eagerly. "But don't stand out there where everybody can hear but me. Come in and sit down."

Now I didn't want to discuss the matter here, and, besides, there was not time. I therefore assumed an air of mystery.

"I can't, Miss Oman. I'm due at the surgery now. But if you should be passing and should have a few minutes to spare, I should be greatly obliged if you would look in. I really don't quite know how to act."

"No, I expect not. Men very seldom do. But you're better than most, for you know when you are in difficulties and have the sense to consult a woman. But what is it about? Perhaps I might be thinking it over."

"Well, you know," I began evasively, "it's a simple matter, but I can't very well—no, by Jove!" I added, looking at my watch, "I must run, or I shall keep the multitude waiting." And with this I bustled away, leaving her literally dancing with curiosity.

CHAPTER IX

THE SPHINX OF LINCOLN'S INN

At the age of twenty-six one cannot claim to have attained to the position of a person of experience. Nevertheless, the knowledge of human nature accumulated in that brief period sufficed to make me feel confident that, at some time during the evening, I should receive a visit from Miss Oman. And circumstances justified my confidence; for the clock yet stood at two minutes to seven when a premonitory tap at the surgery door heralded her arrival.

"I happened to be passing," she explained, and I forbore to smile at the coincidence, "so I thought I might as well drop in and hear what you wanted to ask me about."
