“You’re a genius, Mr. Reeves,” she said when he had finished. “I’m afraid it’s Carmichael that does all the clever work,” he admitted. “Only it’s so difficult to get him to keep up his interest in any subject, he always branches off to something else.” “It’s most exasperating to think that I must actually have been on the same train with my husband, and not noticed anything,” said Miss Rendall-Smith. “Now, let’s see, which part of the train did I come on? Oh, it was the corridor part, I know, because I remember finding I had got into a smoker, and changing my carriage while the train was going. I was rather early for the train, so of course I shouldn’t have seen anybody getting into the Binver slip behind.” “Did Davenant by any chance see you off?” “Yes, he did.” “What sort of journey did you have?” “Oh, we crawled. You know what this line is when there’s a fog on. I never can see why there should be any danger, but we stopped at nearly all the signals. And now you mention it, I remember we did stop just at that curve of the line, a little way before Paston Whitchurch.” “You didn’t see anybody you knew getting out of the train at Binver?” “No, I didn’t notice anybody. But then, I had to go to the Parcels Office about something, so I didn’t go out with the crowd. Oh, it’s maddening to think I’ve been so little use.” “Never mind, I dare say it might have put us off on a false scent if you had seen anybody.” “Mr. Reeves, I think I ought to tell you one other thing, though I dare say you will think it is just my fancy. I have a sort of feeling that I am being watched.” “Being watched?” “Yes. When I took the train to come over to you yesterday, it was rather empty, as these Saturday trains are, and I noticed one of my fellow-passengers, a man who was quite a stranger to me. The curious thing was that he came back from Oatvile by the same train too, and I’m nearly certain, although this may have been just fancy, that I saw the same man watching me from the other side of the street when I went out this morning to go to church.” “This is rather serious. Do you know of anybody who had a grudge against you as well as against your husband?” “Honestly, I can’t think of anybody; you see, our lives have lain so far apart lately. No, I think it’s probably just a coincidence; I was only going to suggest that, if I saw this man again, perhaps I might telephone to you?” “Please do. Just send me word that you’ve seen him again and I’ll come over straight in my car. Then perhaps we shall be able to have a better look at him.”
