“I’m coming to that,” Dangle returned. “We laid our plans for getting hold of the package and with some forged references Susan got a job as servant in your house. She told us that so far as she could see the package would either be about your person or in your safe, and as she couldn’t ascertain the point we laid our plans to find out. As you know, they drew blank, and then we devised the plant on the _Enid_. That worked, but you nearly turned the tables on us in Hopefield Avenue. How you traced us I can’t imagine, and I hope later on you’ll tell me. That night we didn’t know whether we had killed you or not. We didn’t want to and hadn’t meant to, but we might easily have done so. When your body was not found in the morning we became panicky and cleared out. Then there came your attempt of last night. But for an accident it would have succeeded. Now we have come to the conclusion that you are too clever and determined to have you for an enemy. We are accordingly faced with an alternative. Either we must murder you and Miss Merrill or we must get you on to our side. The first we all shrink from, though”—and here Dangle’s eye showed a nasty gleam—“if it was that or our failure we shouldn’t hesitate, but the second is what we should all prefer. In short, Mr. Cheyne, will you and Miss Merrill join us in trading Schulz’s secret: all, including Frau Schulz and Mrs. Price, to share equally? We think that’s a fair offer and we extremely hope you won’t turn us down.” “You haven’t told me if you’ve read the cipher.” “I forgot that. I’m sorry to say that we have not, and that’s another reason we want you and Miss Merrill. We want two fresh brains on it. But the covering letter shows that the secret is in the cipher and it must be possible to read it.” Cheyne did not reply as he sat considering this unexpected move. If he were satisfied as to Arnold Price’s death and if the quartet had been trustworthy he would not have hesitated. Frau Schulz would get her eighth and Mrs. Price would get a quite unexpected windfall. Moreover, the people who worked the invention were entitled to some return for their trouble. No, the proposal was reasonable; in fact it was too reasonable. It was more reasonable than he would have expected from people who had already acted as these four had done. He found it impossible to trust in their _bona fides_. He would like to have Joan Merrill’s views before replying. He therefore temporized. “Your proposal is certainly attractive,” he said, “but before coming to a conclusion Miss Merrill must be consulted. She would be a party to it, same as myself. Suppose we go out and see her now, and then I will give you my answer.” Dangle’s face took on a graver expression.
