A hysterical laugh came from the woman's lips. She flung her hands above her head and went down in a heap, while shriek after shriek of wild, uncanny laughter echoed in the room.


CHAPTER LIV

The blaze of electric lights under their opal shades in Heldon Foyle's office became dim before the growing of the dawn. The superintendent, a cigar between his lips, was working methodically over half-a-dozen piles of papers. At the other side of the table Green puffed furiously at an old brier as he compiled from the documents Foyle handed him a fresh list of witnesses and their statements to be submitted to the Treasury solicitors.

All night the two men had toiled without consciousness of fatigue. Their jigsaw puzzle was at last righting itself. The fragments of the picture had begun to shape clearly. Their efforts had at last been justified. That alone would be their reward. The trial would show little of the labour that the case had cost—only the result. The hard labour of many scores of men would never be handled outside the walls of Scotland Yard. They had nothing to do with the guilt or innocence of the Princess Petrovska. When the case was handed over to the Treasury it would be entirely straightened out, and it would be for them to present the simple issue to the judge and jury at the Old Bailey.

Foyle flung away the remnant of his cigar, and drew out his watch. It was nine o'clock. Sir Hilary Thornton, who had heard of the woman's confession by telephone, might be expected at any moment.

"That ought to do, Green," said the superintendent, as he strung tape round the discarded bundles. "We'll have the lady brought up at the afternoon sitting of the court. That'll give us time to talk it over with the people from the Treasury. Yes, what is it?"

A man had tapped and opened the door. Before he could reply, a slim figure pushed by him. Green rose to his feet and hastily pushed his pipe into his pocket. Foyle raised his eyebrows and stood up more slowly. Lady Eileen Meredith confronted them with wild eyes and pallid face. She swayed a trifle, and the chief inspector with a quick movement placed his arm round her waist and helped her to a chair.
