he already knew from Hester. He walked briskly along the footpath in the warm evening air, the smells of the day sharp around him: horse manure, dry grass and dust from the Heath, now and then the delicacy of meat and onions or the sharpness of peppermint from one peddler or the other. There was the sound of a barrel organ playing a popular song in the distance, and children shouting.
He hailed the first hansom that passed him and gave the driver his address, then instantly changed his mind and directed him instead to his father's home in Primrose Hill.
It was almost dark when he arrived. He walked up the familiar path with a sense of anticipation, even though he had taken no steps to ensure that his father was home, let alone that it was convenient for him to call.
The sweetness of mown grass and deep shadow engulfed him, and a snare of honeysuckle so sharjtit caught in his throat almost like a taste. As he walked around the house and across the lawn to the French doors, he saw that the study light was on. Henry Rathbone had not bothered to draw the curtains and Oliver could see him sitting in the armchair.
Henry was reading and did not hear the silent footsteps or notice the shadow. His legs were crossed, and he was sucking on his pipestem, though as usual the pipe itself had gone out.
Oliver tapped on the glass.
Henry looked up, then as he recognized his son, his lean face filled with pleasure and he beckoned him in.
Oliver felt the ease of familiarity wash over him like a warmth. Unreasonably, some of his helplessness left him, although he had not even begun to explain the problem, let alone address it. He sat down in the big chair opposite his father's, leaning back comfortably.
For a few moments neither of them spoke. Henry continued to suck on his empty pipe. Outside in the darkness a nightbird called and the branches of the honeysuckle, with its trumpet-shaped flowers, waved in the slight wind. A moth banged against the glass.
"I have a new case," Oliver said at length. "I can't possibly win it."
Henry took his pipe out of his mouth. "Then you must have had a good reason for taking it... or at least one that appeared good at the time."
"I don't think it was a good one." Oliver was pedantic, as his nature inclined. He had learned exactness from Henry, and he never measured what he said to him. It was part of the basis of their friendship. "It was compelling. They are not the same."
Henry smiled. "Not in the slightest," he agreed.
"Monk asked me to," Oliver added.
Henry nodded.
"There was a moral imperative," Oliver said, justifying the choice. He did not want his father to think it was because of Monk, still less because of Hester.
"I see. Are you going to tell me what it is?"
"Of course." Oliver moved and crossed his legs comfortably. He gave a succinct outline of the cases against both Cleo Anderson and Miriam Gardiner, then he waited while Henry sat deep in thought for several moments. Outside it was now completely dark except for the patch of luminous moonlight on the grass just short of the old apple tree at the end of the lawn.
"And you assume that this woman Cleo Anderson did not kill the coachman," Henry said at last. "Even in a manner for which there might be some mitigating circumstances - or possibly a struggle in which he died accidentally?"
Oliver thought for a moment before answering. The truth was that that was exactly what he had accepted. Cleo had said she was not present, and he had believed her. He still did.
"Yes. Yes, I am assuming that," he agreed. "She never denied taking the medicines. I have no proof of exactly how she did it, or any of the circumstances. I have deliberately avoided finding them."
Henry made no comment. "How is Monk involved?" he asked instead.
Rathbone explained.
"And Hester?" Henry asked, his voice gentle.
Oliver had not forgotten how fond his father was of Hester, nor his unspoken desire that Oliver should marry her. He sometimes feared Hester's regard for him was at least in part the affection she had for Henry and the desire to belong to a family in which she could know the safety her own had not given her. Her father had shot himself after a financial disgrace visited upon him at the end of the Crimean War by a
