Altogether, by the time he stood on Cleo Anderson’s doorstep in the early-evening sunlight, the shadows so long across the street that they nearly engulfed his feet, he was feeling, as the ostler had remarked, pleased with himself.

Considering that Cleo Anderson had already sacrificed a great deal of her evening answering the questions of Sergeant Robb, she opened the door to Monk with remarkable courtesy. It occurred to him that she might have believed him to be a patient. After all, caring for the sick was her profession.

It took her only a moment to see that he was a stranger, and unlikely to belong to the immediate neighborhood. Nevertheless, she did not dismiss him summarily. Her eyes narrowed a trifle.

"Yes, love, what can I do for you?" she asked, keeping her weight where she could slam the door if he tried to force his way.

He stood well back deliberately.

"Good evening, Mrs. Anderson," he replied. He decided in that moment not to lie to her. "My name is William Monk. Mr. Lucius Stourbridge has employed me to find Miriam Gardiner. As you may be aware, she has disappeared from his house, where she was a guest, and he is frantic with concern for her." He stopped, seeing the anxiety in her face, her rapid breathing and a stiffening of her body. But then, considering Treadwell’s corpse had been found on her path, she could hardly fail to fear for Miriam, unless she already knew that she was safe, not only from physical harm but from suspicion also. Patently, she did not have any such comfort.

"Can you help me?" he said quietly.

For a moment she stood still, making up her mind, then she stepped back, pulling the door wider. "You’d better come in," she invited him reluctantly.

He followed her into a hallway hardly large enough to accommodate the three doors that led from it. She opened the farthest one into a clean and surprisingly light room with comfortable chairs by the fireplace. A row of cupboards lined one wall, all the doors closed and with brass-bound keyholes. None of the keys were present.

"Mr. Stourbridge sent you?" The thought seemed to offer her no comfort. She was still as tense, her hands held tightly, half hidden by her skirts.

He had walked miles and his feet were burning, but to sit unasked would be rushing her, and ill-mannered. "He is terrified some harm may have come to her," he answered. "Especially in light of what happened to the coachman, Treadwell."

In spite of all her effort of control, she drew in her breath sharply. "I don’t know where she is!" Then she steadied herself, deliberately waiting a moment or two. "I haven’t seen her since she left to go and stay in Bayswater. She told me all about that, o’ course." She looked at him levelly.

He had the strong feeling that she was lying, but he did not know to what extent or why. There was fear in her face, but nothing he recognized as guilt. He tried the gentlest approach he could think of.
