“So much I had surmised,” Rathbone replied with the ghost of a smile. He must judge this perfectly. Bawtry was a brilliant man, a star very much in the ascendant, even considered a possible future prime minister by some. He had the background, as well as what appeared to be a blemishless record, and he was fast gaining a formidable political reputation. No doubt within the next few years he would make a fortunate marriage. He had no need to seek money, so he could afford to marry a woman who would be a grace to his social ambitions, and of personal pleasure to him, with wit and charm, perhaps beauty. Rathbone would be a fool to underestimate him. Facing the clever, unflinching eyes he was acutely aware of that.
“Then how can I help you?” Bawtry prompted him.
“Did you see this report of Lambourn’s personally, sir?” Rathbone asked, keeping his voice light, stopping the trembling of it with an effort. “Or did you perhaps take Herne’s word that it was unacceptable?”
Bawtry looked slightly taken aback, as if this were something he had not even considered. “Actually I saw very little of it,” he replied. “He showed me a few pages, and they did seem a bit … haphazard, conclusions drawn without sufficient evidence. He told me the rest was even worse. Since the man was his brother-in-law, he quite naturally wished to protect him from being publicly made a fool of. He wanted to destroy the report without having any more of its weaknesses being known. I could understand that, and frankly I admired it in him. Whether it was for his wife’s sake, or for Lambourn’s was irrelevant to me.”
“But you never saw the rest of it?” Rathbone pressed.
“No. No, I didn’t.” Bawtry stared at him. “What are you suggesting? You wouldn’t be asking me this now unless you believed that it had some relevance to this trial.” The ghost of a smile crossed his face. “Herne didn’t kill Lambourn, if that’s what you’re thinking. He was unquestionably at the dinner in the Atheneum. Aside from personally seeing him there, I could name at least twenty members who were there also and will swear to it.”
Rathbone smiled sadly. “I know that, Mr. Bawtry. Mr. Monk already made absolutely certain of it.”
Bawtry glanced at Monk, then back at Rathbone. “Then I don’t understand what it is you are asking me. I did not read more than a few pages of Lambourn’s report. Incidentally, I believe he was factually right. The use of opium has to be labeled, and its sale in patent medicines restricted to people who have some medical or pharmaceutical knowledge at the least. It was never his conclusions that were in doubt, only the quality of his research, and the way he presented it. He allowed his own anger and pity to destroy his objectivity. To use it in argument for a bill could only have allowed the opponents of it-and they are many and powerful-to have fuel against us.”
“We don’t think the labeling of patent medicines was the issue for which Dr. Lambourn was murdered.” Rathbone cleared his throat. He realized with surprise that his hands-which he was keeping carefully at his sides, out of sight-were clenched so hard that they ached.
Bawtry frowned. “Then what was? And if not that report, then why are you so interested in Herne?”
“If we can be certain that it was not the report on patent medicines for which Lambourn died,” Rathbone replied, and was forced to clear his throat again before he could go on, “that proves that the explanation about the report being a failure and destroying Lambourn was an excuse, a reason to misdirect the investigation. We believe that during the course of his research Lambourn learned something else, something he could not let go of, concerning the sale of pure opium for use in syringes and needles that inject it directly into the blood. The addiction to opium given this way is agonizing and lethal. It was for attempting to have that particular practice made illegal that he was murdered, and Zenia Gadney also.”
Bawtry was pale-faced, his eyes wide. “That’s dreadful! Appalling!” He moved a little in his chair, a slight leaning forward as if he could no longer relax. “Are you suggesting that Herne had something to do with it? How? And for God’s sake …” He trailed off, his eyes filled with dawning horror.
“What is it?” Rathbone demanded urgently.
Bawtry licked his lips, hesitating. He looked profoundly unhappy.
“What is it?” Rathbone repeated, his voice sharpening.
Bawtry looked up and met his eyes. “I’ve noticed rather erratic behavior in Herne,” he said quietly. “One day he’s full of energy and ideas, the next time I see him he looks nervous, can’t concentrate, skin clammy. Is it … is it possible …?” He did not finish the question, but it was not necessary. The idea was already fully understood between them.
Rathbone met his gaze and held it. “You think he may be addicted to opium himself, and either he is the one who is selling it, or else he is the tool of the man who is?”
Bawtry looked wretched. “I hate even to think it of a man I know, but I suppose anyone can fall victim to such a drug, commonly used as it is. Is it possible?” His face already showed that he knew it was.
“That he paid someone to kill Lambourn?” Rathbone asked. “Someone who could do it quietly, easily, making it look like suicide, and who would never be suspected? Yes, of course it is.”
Bawtry was now as tense as Rathbone. Rathbone was suddenly overwhelmingly grateful that Monk was in the room. He had wanted him here as a witness to the conversation, but now he also needed him here for his physical safety.
“Paid someone?” Bawtry affected confusion, but not total disbelief. “Who? Have you discovered something totally new that might attest to this? I have only just arrived in court.”
“A woman,” Rathbone said. “The obvious person who makes complete sense would be Zenia Gadney.”
“Gadney?” Now Bawtry was completely incredulous. “From all accounts I’ve heard, she was a slight, very ordinary middle-aged woman, unremarkable in every way. Indeed, she appears totally a victim, a pawn in the game.” He frowned. “Are you saying she was actually greedy, desperate, and passionate enough to have murdered her husband, the man who had supported her financially, and with some kindness, over the last fifteen years? You must have compelling evidence! It’s frankly preposterous.”
“There is evidence.” Rathbone again chose his words delicately. “It is not compelling, but the more I weigh it, the more it seems to make sense. Consider the possibility that Herne needed desperately to silence Lambourn, indeed, to discredit him so that no whispers of what he found would ever be believed, in case he spoke of it to others. He dare not kill Lambourn himself. Lambourn may even have been aware of the danger and would have taken care not to be alone with Herne. And of course Herne had to have a way of protecting himself from suspicion.”
“I see,” Bawtry said cautiously.
“So he promises to pay Zenia Gadney what would be a moderate sum to him, but a fortune to her, in exchange for this favor.”
“But … murder? Of her husband?” Bawtry was still far from convinced.
“A gentle murder,” Rathbone explained. “She asks Lambourn to meet her alone, when Dinah will not know. There are many ways she could justify such a request. She takes a knife, or a blade of some sort, possibly an open razor. And of course she also takes a strong opium solution, possibly mixed in something palatable, to disguise it. Or it is conceivable Herne gave her a syringe with a solution in it.”
Bawtry nodded, as if he were beginning to believe.
“She arranges a suitable place to meet, possibly in the park,” Rathbone continued. “They walk together up One Tree Hill. On the top the view over the river is worth seeing. She offers him a drink. They have climbed a bit, and he is glad of it. Quite soon he is drowsy and they sit down. He passes out. She then slits his wrists and leaves him to bleed to death. She takes the knife or razor with her, because possibly it can be traced to her. Similarly she takes the container in which she brought the opium. It may well have been quite large. She will have pretended to drink from it herself, in case he found it odd that she didn’t, when she too had walked up the hill.”
