of Monk's silence. "But we have not heard from her since, nor do we know what has happened to her. We are at our wits' end with worry."
"We must look for her!" Lucius cut across them. "Treadwell is dead and Miriam may be in danger. At the very least she must be in fear and distress. You must deploy every man you can to search for her!"
Robb stood still for a moment, surprise taking the words from him. Then slowly he turned to Monk, his eyes narrow and hard. "You omitted to mention that a young woman was a passenger in the carriage when Treadwell was murdered and that she has since disappeared. Why is that, Mr. Monk?"
Monk had foreseen the question, though there was no excuse that was satisfactory, and Robb would know that as well as he did.
"Mrs. Gardiner left with Treadwell," he replied with as honest a bearing as he could. "We have no idea when she left him...."
Lucius was staring at him, his eyes wide and horrified.
"Sophistry!" Robb snapped.
"Reality!" Monk returned with equal harshness. "This was five days ago. If anything happened to Mrs. Gardiner we are far too late to affect it now, except by careful thought and consideration before we act." He was acutely conscious of Lucius and of Harry Stourbridge. Their emotions filled the air. "If she met with violence as well, she would have been found long before now." He did not glance at either of them but kept his eyes level on Robb. "If she was kidnapped, then a ransom will be asked for, and it has not so far. If she witnessed the murder, then she may well have run away, for her own safety, and we must be careful how we look for her, in case we bring upon her the very harm she fears." He drew in his breath. "And until Major Stourbridge identified the body as that of Treadwell, we did not know that it was anything more than a domestic misunderstanding between Mr. Stourbridge and Mrs. Gardiner."
Lucius stood appalled.
Stourbridge looked from one to the other of them. "We know now," he said grimly. "The question is what we are to do next."
"Discover all the facts that we can," Monk answered him. "And then deduce what we can from them."
Robb bit his lip, his face pale. He turned to Lucius. "You have no idea why Mrs. Gardiner left your home?"
"No, none at all," Lucius said quickly. "There was no quarrel, no incident at all which sparked it. Mrs. Gardiner was standing alone, watching the croquet match when, without warning or explanation, she simply left."
"With Treadwell?"
"She left in the carriage," Stourbridge corrected him. "She could hardly have driven it herself."
A flash of irritation crossed Robb's face and then disappeared, as if he had remembered their distress. "Had Mrs. Gardiner any previous acquaintance with Treadwell, perhaps through the cook?"
"No," Lucius said instantly. "She had met no one in the house before I first took her there."
"Where did you meet Mrs. Gardiner?"
"On Hampstead Heath. Why? It is natural enough that he should bring her back here. She lives on Lyndhurst Road."
Robb pursed his lips. "That is about three quarters of a mile from where the carriage was found, and rather more from where TreadwelPs body was. I assume you have already been to her home to see if she was there?"
"Of course! No one has seen her since she left to come to Bayswater," Lucius answered. "It is the first place we looked. Please, tell us what you know of Treadwell's death, I beg you."
They were outside in the street again now. Lucius stood breathing deeply, as if trying to clear his lungs of the choking air of the morgue with its close smell of death. Even so, he did not take his eyes from Robb's face.
"We know nothing except that he was murdered," Robb replied. "We did not even know his name until you gave it to us, although from his clothes we assumed his occupation."
"Was there nothing found in the carriage?" Stourbridge asked with a frown. "No marks or stains to indicate where it had been? What about the horses? Are they hurt?"
"No, they were lost, confused, aware mat something was wrong. There was nothing to indicate they had bolted. The harness was not broken. The reins were still tied to the bar, as if the driver had stopped, then climbed down rather than fallen. The carriage itself has no scratches or marks but those of ordinary use."
