"Never mind that. It is necessary it should be searched to-night. Even you'll acknowledge it's significant that all day when she has been downstairs her door has been locked."
"It's only significant," Bobby flashed, "in view of your treatment of her yesterday."
Robinson grinned.
"That will hardly go down. Rawlins has hesitated to break in. I've instructed him to do it now, if necessary. For the last time, will you bring your cousin down? Will you go through and unlock the door leading from the old bedroom to the private hall so we can get up?"
"No," Bobby cried, "I wouldn't do it if I believed you were right. And I know you're wrong."
"Prove that we're wrong. Clear your cousin by helping us,"
Robinson urged.
"Since you're so determined," Graham said quietly, "I'll do it."
"Hartley! What are you thinking of?"
"Of showing them how wrong they are," Graham said. "I'll tell her Doctor Groom wishes to speak to her about Mr. Blackburn. I'll warn him to keep her downstairs for a quarter of an hour. That should give you plenty of time."
Robinson nodded.
