"I am going out of London."

He was astonished.

"But your house—in Harley Street—so central...." he stammered. "I don't understand. Are you giving up your practice?"

"Of course."

"At your age, Dr. Harden?"

"What has age got to do with it? There is no such thing as age."

He stared. Then his eyes turned to Alice.

"No such thing as age?" he murmured helplessly. "But surely you are not going to sell; you have the best house in Harley Street. Its commanding position ... in the centre of that famous locality...."

"Do you think that any really sane man would live in the centre of Harley Street," I asked calmly. "Is he likely to find any peace in that furnace of crude worldly ambitions? But all that is already a thing of the past. In a few weeks, Franklyn, Harley Street will be deserted."

"Deserted?" His eyes rolled.
