"Well, perhaps it isn't," Charles said consolingly. "Peter and I have got to go over to the police-station to-morrow, and we may hear something fresh then. At present we only know that the doctor wasn't satisfied, and is going to conduct a post mortem."
"Please tell us just what happened!" Margaret begged.
Charles made the story as short as possible, and he did not mention the doctor's discovery. At the end of his tale Celia said: "If anyone killed him it was the Monk, and now we know for certain he's not a ghost. Well, I always said I wasn't scared of flesh and blood, but do you think it's safe for us here?"
"Yes, I think so," her brother replied. "If the Monk did murder Duval it's fairly certain he did it because Duval had discovered his identity. Or even because he knew Duval had been talking to us. He isn't likely to try to do any of us in. Too risky, for one thing, and for another, no motive."
"How could he have known that Duval had talked to us?" Margaret asked. "Do you think he followed him here this evening?"
"Duval undoubtedly thought that possible. It would be easy for him to find out that we'd had dealings with Duval without that, though. I never made any secret of the fact that I visited him, and all sorts of people have seen me talking to him at various times," Charles said. "Wilkes, Ackerley, the Rootes - they all knew, not to mention various locals who've seen Duval and me together at the Bell."
"And, from what you told us to-day, Mr. Strange as well," Margaret said, meeting her brother's eye.
"Yes, Strange, too." Charles glanced at his watch. "Well, I don't know how the rest of you feel, but I'm all for bed."
Margaret got up rather reluctantly. "Yes, I suppose we'd better try and get some sleep," she agreed. "But I do wish we weren't so much in the dark still. Well, good night, you two. Coming, Peter?"
Brother and sister went out together, and soon quiet descended on the house.
