"I'll repeat it when you like," answered Ivan, squaring his shoulders. "Now you say that you want to prove Mr. Grell's innocent I have nothing to hide. For I am certain that he is innocent."
"Tell me one other thing," said the superintendent.
"What is the association between Petrovska and Grell? Why should she have taken part in this business?"
Ivan spread out his white hands. "That you must find out either from Mr. Grell or her. I don't know."
Foyle drew out his watch. "All right, Ivan. I'll see you again shortly. Meanwhile, I'll send some one along to get your statement. I don't think you'll regret having decided to speak. Good-bye."
CHAPTER LI
Both Sir Hilary Thornton and Chief Inspector Green were waiting for Heldon Foyle when he returned to his office. The superintendent darted a question at the chief inspector as he flung off his overcoat.
"Yes, sir," answered Green. "She's at Malchester Row now. There was no trouble at all. She came up to the Grange at half-past three, in a car, and asked the maid who answered the door for Mrs. Ellis. The girl showed her into a sitting-room, acting on my instructions, and I walked in on her and told her I should detain her. She was angry at first, but in a moment or two she laughed, and asked if Mr. Grell was taken. That was all there was to it. I brought her back straight away by train. She seemed to treat it as a joke, but never a word about the case did she utter."
