Mr. Quarterpage nudged Spargo.

"That's something I couldn't have done!" he remarked. "As I told you, she'd disappeared from Brighton when enquiries were made after Maitland's release."

"Here you are," said Mr. Cooper. "I sent six copies of that photograph to Miss Baylis in April, 1895. Her address was then 6, Chichester Square, Bayswater, W."

Spargo rapidly wrote this address down, thanked the photographer for his courtesy, and went out with Mr. Quarterpage. In the street he turned to the old gentleman with a smile.

"Well, I don't think there's much doubt about that!" he exclaimed.

"Maitland and Marbury are the same man, Mr. Quarterpage. I'm as certain of that as that I see your Town Hall there."

"And what will you do next, sir?" enquired Mr. Quarterpage.

"Thank you--as I do--for all your kindness and a.s.sistance, and get off to town by this 1.20," replied Spargo. "And I shan't fail to let you know how things go on."

"One moment," said the old gentleman, as Spargo was hurrying away, "do you think this Mr. Aylmore really murdered Maitland?"

"No!" answered Spargo with emphasis. "I don't! And I think we've got a good deal to do before we find out who did."

Spargo purposely let the Marbury case drop out of his mind during his journey to town. He ate a hearty lunch in the train and talked with his neighbours; it was a relief to let his mind and attention turn to something else than the theme which had occupied it unceasingly for so many days. But at Reading the newspaper boys were shouting the news of the arrest of a Member of Parliament, and Spargo, glancing out of the window, caught sight of a newspaper placard:

THE MARBURY MURDER CASE ARREST OF MR. AYLMORE

He s.n.a.t.c.hed a paper from a boy as the train moved out and; unfolding it, found a mere announcement in the s.p.a.ce reserved for stop-press news:

"Mr. Stephen Aylmore, M.P., was arrested at two o'clock this afternoon, on his way to the House of Commons, on a charge of being concerned in the murder of John Marbury in Middle Temple Lane on the night of June 21st last. It is understood he will be brought up at Bow Street at ten o'clock tomorrow morning."

Spargo hurried to New Scotland Yard as soon as he reached Paddington.

He met Rathbury coming away from his room. At sight of him, the detective turned back.

"Well, so there you are!" he said. "I suppose you've heard the news?"

Spargo nodded as he dropped into a chair.

"What led to it?" he asked abruptly. "There must have been something."

"There was something," he replied. "The thing--stick, bludgeon, whatever you like to call it, some foreign article--with which Marbury was struck down was found last night."

"Well?" asked Spargo.

"It was proved to be Aylmore's property," answered Rathbury. "It was a South American curio that he had in his rooms in Fountain Court."

"Where was it found?" asked Spargo.

Rathbury laughed.

"He was a clumsy fellow who did it, whether he was Aylmore or whoever he was!" he replied. "Do you know, it had been dropped into a sewer-trap in Middle Temple Lane--actually! Perhaps the murderer thought it would be washed out into the Thames and float away. But, of course, it was bound to come to light. A sewer man found it yesterday evening, and it was quickly recognized by the woman who cleans up for Aylmore as having been in his rooms ever since she knew them."

"What does Aylmore say about it?" asked Spargo. "I suppose he's said something?" "Says that the bludgeon is certainly his, and that he brought it from South America with him," announced Rathbury; "but that he doesn't remember seeing it in his rooms for some time, and thinks that it was stolen from them."

"Um!" said Spargo, musingly. "But--how do you know that was the thing that Marbury was struck down with?"

Rathbury smiled grimly.

"There's some of his hair on it--mixed with blood," he answered. "No doubt about that. Well--anything come of your jaunt westward?"

"Yes," replied Spargo. "Lots!"

"Good?" asked Rathbury.

"Extra good. I've found out who Marbury really was."

"No! Really?"

"No doubt, to my mind. I'm certain of it."

Rathbury sat down at his desk, watching Spargo with rapt attention.

"And who was he?" he asked.

"John Maitland, once of Market Milcaster," replied Spargo. "Ex-bank manager. Also ex-convict."

"Ex-convict!"

"Ex-convict. He was sentenced, at Market Milcaster Quarter Sessions, in autumn, 1891, to ten years' penal servitude, for embezzling the bank's money, to the tune of over two hundred thousand pounds. Served his term at Dartmoor. Went to Australia as soon, or soon after, he came out.

That's who Marbury was--Maitland. Dead--certain!"

Rathbury still stared at his caller.

"Go on!" he said. "Tell all about it, Spargo. Let's hear every detail.

I'll tell you all I know after. But what I know's nothing to that."

Spargo told him the whole story of his adventures at Market Milcaster, and the detective listened with rapt attention.

"Yes," he said at the end. "Yes--I don't think there's much doubt about that. Well, that clears up a lot, doesn't it?"

Spargo yawned.

"Yes, a whole slate full is wiped off there," he said. "I haven't so much interest in Marbury, or Maitland now. My interest is all in Aylmore."

Rathbury nodded.

"Yes," he said. "The thing to find out is--who is Aylmore, or who was he, twenty years ago?"

"Your people haven't found anything out, then?" asked Spargo.

"Nothing beyond the irreproachable history of Mr. Aylmore since he returned to this country, a very rich man, some ten years since,"

answered Rathbury, smiling. "They've no previous dates to go on. What are you going to do next, Spargo?"
