“My own foible is to walk the streets at night,” said Northcote. “That is the only taste of real freedom one enjoys in a city. It is only during the middle of the night in a place like London that one can think one’s own thoughts and breathe God’s air. But as we do not appear quite to have settled this momentous business of the brief, which may mean so much more to society at large than you can imagine, I will enter your domain and drink one glass of your whiskey.”

The solicitor led the way thereto, unlocked the front door with a latch-key, and Northcote found himself in the interior of a modern dwelling-house. It was furnished with perfect taste, fitted with every luxury. The heavy mats on the floors muffled the sounds of his feet; the warmed air that assailed his nostrils was seductive and delicate after the bitter inclemency from which he had taken refuge. Numerous objects of vertu were scattered in every nook, and the walls were lined with pictures that astonished him beyond measure.

“Why, that is a Whistler—one of the two or three!” he exclaimed, as he passed in the hall an unpretentious-looking portrait.

“I got it years ago for a song, before they began to be bought,” said Mr. Whitcomb modestly.

“And what is that stuck over the stairs? From this distance it looks suspiciously like a Velasquez. But surely that is in the Prado?”

“Aren’t you confounding it with the companion picture?”

“I had no idea we had this in England.”

“We have many things in England which fortunately are not matters of common knowledge. Every year they are becoming rarer, owing to that scourge of nations, the press. If you value my regard, you will forget that you have noticed it.”

“Did you get that also before they began to be bought?”

“There is rather a strange story attaching to that picture.”
