"Yes, we know; and we have discovered the reason why Moxton was killed. Surely you have forgotten our talk about the forged bill. Before the end of the present week the murderer will have confessed, Mrs. Moxton will be exonerated from all complicity in her husband's death, and you, Mr. Busham--well, I don't know about you. But from what I guess of your share in this tragedy, you will be in gaol."
"I had nothing to do with it. Who killed Moxton?"
"Oh," laughed Cass, delighted at the confusion of Busham, "as you know there is no need to tell you the name."
The baffled lawyer looked in turn at each of the scornful faces. Then he rose in a hurry. "This is a game of bluff," he cried savagely. "You do not know who murdered Edgar, and you are trying to get my secret from me without paying for it. Oh, I know you all; I can see through you."
"It does you credit," said Janet, contemptuously.
"Sneer and jeer as much as you like, madam, you will not look so merry when your sister is in prison on a charge of murder."
"Which she never will be," put in Ellis.
"We shall see, we shall see. You think yourself a clever man, doctor, do you not? But I am cleverer. Oh, you don't know what I am. You gave me five days to confess, as you call it, or else threatened to put the matter into the hands of the police. The five days are up."
"Quite so," said Ellis, smoothly, "and as you won't hear reason I shall see the police to-morrow."
"I dare you to! I dare you to!" foamed Busham, who had completely lost his temper. "I get my price, or Mrs. Moxton goes to gaol."
