"Where?" exclaimed Inspector Chippenfield, with an indignant start.

"Up there behind that pillar there—no, the next one. See, he's looking down at you."

Crewe caught the inspector's eye, and nodded and smiled in a friendly fashion, but Inspector Chippenfield returned the salutation with a haughty glare.

"The impudence of that chap is beyond belief," he said to his subordinate. "One would have thought he'd have kept away from court after his wild-goose chase to Scotland and piling up expenses, but not him! Brazen impudence is the stock-in-trade of the private detective. If Scotland Yard had a little more of the impudence of the private detective, Rolfe, we should be better appreciated."

"I suppose he's come in the hopes of seeing the jury acquit Birchill," said Rolfe.

"No doubt," replied Inspector Chippenfield. "But he's come to the wrong shop. A good jury should convict without leaving the box if the case is properly put before them by the prosecution. Crewe would like to triumph over us, but it is our turn to win."

But Inspector Chippenfield was wrong in thinking that Crewe's presence in court was due to a desire for the humiliation of his rivals. Crewe had spent most of the previous night reading and revising his summaries and notes of the Riversbrook case, and in minutely reviewing his investigations of it. Over several pipes in the early morning hours he pondered long and deeply on the secret of Sir Horace Fewbanks's murder, without finding a solution which satisfactorily accounted for all the strange features of the case. But one thing he felt sure of was that Birchill had not committed the murder. He based that belief partly on the butler's confession, and partly on his own discoveries. He believed Hill to be a cunning scoundrel who had overreached the police for some purpose of his own by accusing Birchill, and who, to make his story more probable, had even implicated himself in the supposed burglary as a terrorised accomplice. And Crewe had been unable to test the butler's story, or find out what game he was playing, because of the assiduity with which the principal witness for the prosecution had been "nursed" by the police from the moment he made his confession. Crewe bit hard into his amber mouthpiece in vexation as he recalled the ostrich-like tactics of Inspector Chippenfield, who, having accepted Hill's story as genuine, had officially baulked all his efforts to see the man and question him about it.

He had come to court with the object of witnessing Birchill's behaviour in the dock and the efforts of any of his criminal friends to communicate with him. As a man who had had considerable experience in criminal trials he knew the irresistible desire of the criminal in the gallery of the court to encourage the man in the dock to keep up his courage. Communications of the kind had to be made by signs. It was Crewe's impression that by watching Birchill in the dock and Birchill's friends in the gallery he might pick up a valuable hint or two. It was also his intention to study closely the defence which Counsel for the prisoner intended to put forward.

It was therefore with a feeling of mingled annoyance and surprise that Crewe, looking down from his point of vantage at the bevy of fashionably-dressed ladies in the body of the court, recognised Mrs. Holymead, Mademoiselle Chiron and Miss Fewbanks seated side by side, engaged in earnest conversation. Before he could withdraw from their view behind the pillar in front of him, Miss Fewbanks looked up and saw him. She bowed to him in friendly recognition, and Crewe saw her whisper to Mrs. Holymead, who glanced quickly in his direction and then as quickly averted her gaze. But in that fleeting glance of her beautiful dark eyes Crewe detected an expression of fear, as though she dreaded his presence, and he noticed that she shivered slightly as she turned to resume her conversation with Miss Fewbanks.

His Honour Mr. Justice Hodson entered, and the persons in the court scrambled hurriedly to their feet to pay their tribute of respect to British law, as exemplified in the person of a stout red-faced old gentleman wearing a scarlet gown and black sash, and attended by four of the Sheriffs of London in their fur-trimmed robes. The judge bowed in response and took his seat. The spectators resumed theirs, craning their necks eagerly to look at the accused man, Birchill, who was brought into the dock by two warders. The work of empanelling a jury commenced, and when it was completed Mr. Walters, K.C., opened the case for the prosecution.
