He sauntered quite casually along the pavement next to a small space of open grass and bought a beef-and-onion sandwich from a stall. It was fresh, and he ate it with considerable enjoyment. He bought a second and enjoyed that as well. He wondered how Robb had traced Mrs. Whitbread. That was a good piece of detection. It commanded his respect, and he gave it willingly. He liked Robb and admired the young man’s care for his grandfather.

He must stay within sight of Mr. Hornchurch’s house so he could see when the housekeeper left, but not so close that Robb, when returning, would observe him.

He expected Robb to come back the way he had seen him leave, so he was jolted by considerable surprise when he heard Robb’s voice behind him, and he swung around to see him only a yard away, his face grim, his mouth pulled tight.

"Waiting for me, Inspector Monk?" he said coldly.

Monk felt as if he had been slapped. In one sentence, Robb had shown that he had learned Monk’s history in the police and his reputation both for skill and for ruthlessness. It was there in Robb’s face now as he stood in sunlight dappled by the trees, his eyes guarded, challenging. Monk could see the anger in him—and something else which he thought might be fear.

Was there any point in lying? He did not want to make an enemy of Robb, for practical reasons as well as emotional ones; in fact, he could not afford to. The first concern was Miriam. Her freedom, even her life, might depend upon this. And he had no idea whether she was guilty of anything or not. She might have killed Treadwell. On the other hand she might be in danger herself, terrified and running. He knew no more of the truth now than he had when Lucius Stourbridge had walked into his rooms a few days before.

He shifted his weight to stand a little more casually. He raised his eyebrows. "Actually, I’d really been hoping to avoid you," he said truthfully.

Robb’s mouth curled downward. "You thought I’d come back the way I left? I would have if I hadn’t seen you, and I admit, that was only chance. But I know this area better than you do. I have the advantage. I wondered if you’d follow me. It would seem the obvious thing to do if you had no ideas yourself." There was a contempt in his voice that stung. "Why did you wait here for me? I suppose you already knew I would be going to my grandfather."

Monk was startled—and surprised to find himself also hurt. He had not earned that from Robb. Certainly, he was trying to beat Robb to Miriam, but that was what Lucius Stourbridge had hired him for. Robb would not have expected him to do less.

"Of course, I knew where you were going," Monk answered, keeping his voice level and almost expressionless. "But the reason I didn’t go after you was because I wasn’t following you in the first place. Does it surprise you so much that my investigations should bring me to the same place as yours?"
