"Perhaps. Lots of men would like to be engaged to Rosie. As if Rosie would think of the likes of him!"
"But they kept up some kind of acquaintance?"
"Oh, yes, she let 'im come to see 'er at 'er flat sometimes, but she wouldn't go out with him, or anything like that. And she didn't 'ave 'im very often. I don't think she 'ad the heart to send him away for good, you see. She was letting 'im down gently, I think. But I'm not sure about all that, you know. I didn't go to see Rosie often myself. Not that she wasn't nice to me, but it wasn't fair on 'er. She didn't want a common old woman like me round, and 'er hobnobbin' with lords and things."
"Why did you not tell the police at once that Sorrell was threatening your daughter?"
"I thought about it, and then I thought, in the first place, I 'adn't any proof. Judging by the way you treated me today, I should think I was right. And in the second place, even supposing the police shut 'im up, they couldn't shut 'im up for good. He would just do 'er in when he came out. And I couldn't be always round watching 'im. So I thought it best to do it when I could. I 'ad that little knife, and I thought that would be a good way. I don't know anything about pistols and things."
"Tell me, Mrs. Wallis, did your daughter ever see that dagger?"
"No."
"Are you quite sure? Think a little."
"Yes; she did. I'm telling you a lie. When she was quite big, before she left school, they had a play of Shakespeare that had a dagger in it. I don't remember the name of it."
" Macbeth? " suggested Grant.
