'If he was innocent, then why was he found with the dying man? Could he have done nothing to stop the crime? Knowing the Wardales as I do, I would believe them capable of anything.' The words flowed easily out of her. It surprised her, for she had not meant to come so close to revealing her own past.
He stared at her in disapproval. 'You can know nothing of that family. They were turned out of their home in disgrace and no doubt underwent hardships that were not in proportion to the crime. Think of it, Diana. A mother and three children. Two of them girls. Lord knows what happened to them. And if the father was innocent, all along...'
And for a moment, she put aside her own story, and thought of Marc's bride, Nell, Helena Wardale, and the past that she was so careful not to speak of. 'Perhaps you are right. Some members of the family have suffered unjustly.'
'How gracious of you to admit it.' Again, she was surprised by his passion on the subject, and his harsh tone stung her. Then he seemed to realize how he sounded, for he calmed. 'Please forgive my outburst. It was uncalled for. Even if the matter was important, you are right that it is the distant past. It hardly concerns us.' And for a moment, his face took on a funny cast. 'But the events of twenty years ago are about to return to haunt the families involved. I came to speak to Marc Carlow to offer a word of warning that the truth was likely to come out in the near future, and to be on his guard. But it would be better for all concerned, if Narborough had any part in what happened, that he admits the fact so that his family might prepare themselves for it.'
'But what makes you think this is the case, and what does it have to do with you?'
'I can explain very little, I am afraid. Other than that I am sure of my facts. And I mean to gather the evidence necessary to prove them.' He squeezed her hand, as though wanting to assure himself that she was still his. 'Is that so very wrong?'
'If Lord Narborough is truly a murderer? Then I suppose it is not. But Nathan?' She squeezed his hand in return. 'He is not guilty. I am as sure of that fact, as you are of his guilt.'
And suddenly, there was a strange light in his eyes. 'Then you would have to prove it to me. If he is as innocent as Leybourne was, I would be making a horrible mistake in accusing him. If there is some way that I can be sure... You are an intimate of the family. If you have a way to assure me, other than conjecture...'
She pulled her hand away. 'Are you asking me to spy on my friends?'
He looked alarmed. 'Certainly not. And I never intended to suggest such a thing. It was an idle thought, nothing more. I meant what I said at first, when I refused your help. It would be too difficult for you. And possibly dangerous, should it turn out that I was right. I would be asking you to face a murderer in my stead. It makes me uncomfortable enough to know that you live with them. For all your confidence, I am not sure of their intentions.'
'You think they are a threat to me? Surely not. Lord and Lady Narborough have been nothing but good to me, as has the rest of the family.'
He touched her shoulder to reassure her. 'My problem is not with the rest of his family. They are no more to blame than the Wardales were. Those girls were no different from Honoria and Verity. Little more than babes when it all occurred, and God knows what happened to them.'
She thought again of the haunted look in Nell's eyes when she had first come to them. 'If their father was innocent, they deserved better than they received.'
His face clouded. 'You deserve better as well. A life of ease and not labour. But you are content, because your work is honourable. Perhaps it is true of them as well.'
'Or perhaps not,' she said, and watched as his expression became even more glum. And suddenly, it occurred to her why he might be so interested in the Wardales. He must have some knowledge of Nell's sister, Rosalind. A tendre, perhaps? If she was part of the secret he did not wish to share, it must have ended tragically. Did he blame himself? Perhaps the mysterious stranger he mentioned was their brother, Mr Wardale.
'I think I can see why you are obsessed with the crime and its aftermath.' Though she had vowed to him that she would not be suspicious or question him about his past, she wondered all the same. If her surmise was correct, she feared a visit from the mysterious stranger, almost as much as Nathan did. 'And now that you have put the idea in my head, I doubt I will be satisfied until I know the truth about the Earl of Leybourne. Although I am sure that Lord Narborough did them no harm. And I think there is a way I can assure you, that will do very little harm to anyone.'
