“Here it is, gentlemen,” said the man, opening the cab door.

Allan and Allan’s adviser both got out, and both looked at the house, with the same feeling of instinctive distrust.

Buildings have their physiognomy—especially buildings in great cities—and the face of this house was essentially furtive in its expression. The front windows were all shut, and the front blinds were all drawn down. It looked no larger than the other houses in the street, seen in front; but it ran back deceitfully and gained its greater accommodation by means of its greater depth. It affected to be a shop on the ground-floor; but it exhibited absolutely nothing in the space that intervened between the window and an inner row of red curtains, which hid the interior entirely from view. At one side was the shop door, having more red curtains behind the glazed part of it, and bearing a brass plate on the wooden part of it, inscribed with the name of “Oldershaw.” On the other side was the private door, with a bell marked Professional; and another brass plate, indicating a medical occupant on this side of the house, for the name on it was, “Doctor Downward.” If ever brick and mortar spoke yet, the brick and mortar here said plainly, “We have got our secrets inside, and we mean to keep them.”

“This can’t be the place,” said Allan; “there must be some mistake.”

“You know best, sir,” remarked Pedgift Junior, with his sardonic gravity. “You know Mrs. Mandeville’s habits.”

“I!” exclaimed Allan. “You may be surprised to hear it; but Mrs. Mandeville is a total stranger to me.”

“I’m not in the least surprised to hear it, sir; the landlady at Kingsdown Crescent informed me that Mrs. Mandeville was an old woman. Suppose we inquire?” added the impenetrable Pedgift, looking at the red curtains in the shop window with a strong suspicion that Mrs. Mandeville’s granddaughter might possibly be behind them.

They tried the shop door first. It was locked. They rang. A lean and yellow young woman, with a tattered French novel in her hand, opened it.

“Good-morning, miss,” said Pedgift. “Is Mrs. Mandeville at home?”

The yellow young woman stared at him in astonishment. “No person of that name is known here,” she answered, sharply, in a foreign accent.
