"Did you never, in all your experience, know a case where the law made a mistake?"

"Yes, several," Grant admitted cheerfully. "But they were all cases of mistaken identity. And that's not in question here."

"No; but there must be cases where the evidence is nothing but a lot of things that have nothing to do with each other put together until they look like something. Like a patchwork bedcover."

She was getting too «hot» to be comfortable in her search after enlightenment, and Grant reassured her and unostentatiously changed the subject — and presently fell silent; a sudden idea had occurred to him. If he went down to Eastbourne alone, Mrs. Ratcliffe, however casual his appearance, might be suspicious of his bona fides. But if he appeared with a woman companion he would be accepted at once as off duty, and any suspicion his presence might arouse would be lulled until he could get Mrs. Ratcliffe completely off her guard. And the whole success of the expedition depended on that — that she should be unprepared for any demonstration on his part.

"Look here," he said, "are you doing anything this afternoon?"

"No; why?"

"Have you done your good deed for the day?"

"No, I think I've been entirely selfish today."

"Well, get it off your chest by coming down to Eastbourne with me this afternoon as my cousin, and being my cousin till dinner. Will you?"

She considered him gravely. "I don't think so. Are you on the track of some other unhappy person?"
