I looked at Ruth to see what she wished.

"If you won't think me ungrateful," said she, "I should rather be alone with my father to-night. He is very weak, and--"

"Yes, I understand," I said hastily. And I did. Mr. Bellingham was a man of strong emotions and would probably be somewhat overcome by the sudden change of fortune and the news of his brother's tragic death.

"In that case," said Thornd.y.k.e, "I will bespeak your services. Will you go on and wait for me at my chambers, when you have seen Miss Bellingham home?"

I agreed to this, and we set forth under the guidance of Dr. Norbury (who carried an electric lamp) to return by the way we had come; two of us, at least, in a vastly different frame of mind. The party broke up at the entrance gates, and as Thornd.y.k.e wished my companion "Good night,"

she held his hand and looked up in his face with swimming eyes.

"I haven't thanked you, Doctor Thornd.y.k.e," she said, "and I don't feel that I ever can. What you have done for me and my father is beyond all thanks. You have saved his life and you have rescued me from the most horrible ignominy. Good-bye! and G.o.d bless you!"

The hansom that bowled along eastward--at most unnecessary speed--bore two of the happiest human beings within the wide boundaries of the town.

I looked at my companion as the lights of the street shone into the cab, and was astonished at the transformation. The pallor of her cheek had given place to a rosy pink; the hardness, the tension, the haggard self-repression that had aged her face, were all gone, and the girlish sweetness that had so bewitched me in the early days of our love had stolen back. Even the dimple was there when the sweeping lashes lifted and her eyes met mine in a smile of infinite tenderness. Little was said on that brief journey. It was happiness enough to sit, hand clasped in hand, and know that our time of trial was past; that no cross of Fate could ever part us now.

The astonished cabman set us down, according to instructions, at the entrance to Nevill's Court, and watched us with open mouth as we vanished into the narrow pa.s.sage. The court had settled down for the night, and no one marked our return; no curious eye looked down on us from the dark house-front as we said "Good-bye" just inside the gate.

"You will come and see us to-morrow, dear, won't you?" she asked.

"Do you think it possible that I could stay away, then?"

"I hope not. But come as early as you can. My father will be positively frantic to see you; because I shall have told him, you know. And, remember, that it is you who have brought us this great deliverance.

Good night, Paul."

"Good night, sweetheart."

She put up her face frankly to be kissed and then ran up to the ancient door; whence she waved me a last good-bye. The shabby gate in the wall closed behind me and hid her from my sight; but the light of her love went with me and turned the dull street into a path of glory.

CHAPTER XIX

A STRANGE SYMPOSIUM

It came upon me with something of a shock of surprise to find the sc.r.a.p of paper still tacked to the oak of Thornd.y.k.e's chambers. So much had happened since I had last looked on it that it seemed to belong to another epoch of my life. I removed it thoughtfully and picked out the tack before entering, and then, closing the inner door, but leaving the oak open, I lit the gas and fell to pacing the room.

What a wonderful episode it had been! How the whole aspect of the world had been changed in a moment by Thornd.y.k.e's revelation! At another time, curiosity would have led me to endeavour to trace back the train of reasoning by which the subtle brain of my teacher had attained this astonishing conclusion. But now my own happiness held exclusive possession of my thoughts. The image of Ruth filled the field of my mental vision. I saw her again as I had seen her in the cab with her sweet, pensive face and downcast eyes; I felt again the touch of her soft cheek and the parting kiss by the gate, so frank and simple, so intimate and final.

I must have waited quite a long time, though the golden minutes sped unreckoned, for when my two colleagues arrived they tendered needless apologies.

"And I suppose," said Thornd.y.k.e, "you have been wondering what I wanted you for."

I had not, as a matter of fact, given the matter a moment's consideration.

"We are going to call on Mr. Jellicoe," Thornd.y.k.e explained. "There is something behind this affair, and until I have ascertained what it is, the case is not complete from my point of view."

"Wouldn't it have done as well to-morrow?" I asked.

"It might; and then it might not. There is an old saying as to catching a weasel asleep. Mr. Jellicoe is a somewhat wide-awake person, and I think it best to introduce him to Inspector Badger at the earliest possible moment."

"The meeting of a weasel and a badger suggests a sporting interview,"

remarked Jervis. "But you don't expect Jellicoe to give himself away, do you?"

"He can hardly do that, seeing that there is nothing to give away. But I think he may make a statement. There were some exceptional circ.u.mstances, I feel sure."

"How long have you known that the body was in the Museum?" I asked.

"About thirty or forty seconds longer than you have, I should say."

"Do you mean," I exclaimed, "that you didn't know until the negative was developed?"

"My dear fellow," he replied, "do you suppose that, if I had had certain knowledge where the body was, I should have allowed that n.o.ble girl to go on dragging out a lingering agony of suspense that I could have cut short in a moment? Or that I should have made these humbugging pretences of scientific experiments if a more dignified course had been open to me?"

"As to the experiments," said Jervis, "Norbury could hardly have refused if you had taken him into your confidence."

"Indeed he could, and probably would. My 'confidence' would have involved a charge of murder against a highly respectable gentleman who was well known to him. He would probably have referred me to the police, and then what could I have done? I had plenty of suspicions, but not a single solid fact."

Our discussion was here interrupted by hurried footsteps on the stairs and a thundering rat-tat on our knocker.

As Jervis opened the door, Inspector Badger burst into the room in a highly excited state.

"What is all this, Doctor Thornd.y.k.e?" he asked. "I see you've sworn an information against Mr. Jellicoe, and I have a warrant to arrest him; but before anything is done I think it right to tell you that we have more evidence than is generally known pointing to quite a different quarter."

"Derived from Mr. Jellicoe's information," said Thornd.y.k.e. "But the fact is that I have just examined and identified the body at the British Museum, where it was deposited by Mr. Jellicoe. I don't say that he murdered John Bellingham--though that is what the appearances suggest--but I do say that he will have to account for his secret disposal of the body."

Inspector Badger was thunderstruck. Also he was visibly annoyed. The salt which Mr. Jellicoe had so adroitly sprinkled on the constabulary tail appeared to develop irritating properties, for when Thornd.y.k.e had given him a brief outline of the facts he stuck his hands in his pockets and exclaimed gloomily:

"Well, I'm hanged! And to think of all the time and trouble I've spent on those d.a.m.ned bones! I suppose they were just a plant?"

"Don't let us disparage them," said Thornd.y.k.e. "They have played a useful part. They represent the inevitable mistake that every criminal makes sooner or later. The murderer will always do a little too much. If he would only lie low and let well alone, the detective might whistle for a clue. But it is time we were starting."

"Are we all going?" asked the inspector, looking at me in particular with no very gracious recognition.

"We will all come with you," said Thornd.y.k.e; "but you will, naturally, make the arrest in the way that seems best to you."

"It's a regular procession," grumbled the inspector; but he made no more definite objection, and we started forth on our quest.

The distance from the Temple to Lincoln's Inn is not great. In five minutes we were at the gateway in Chancery Lane, and a couple of minutes later saw us gathered round the threshold of the stately old house in New Square.

"Seems to be a light in the first floor front," said Badger. "You'd better move away before I ring the bell."

But the precaution was unnecessary. As the inspector advanced to the bell-pull a head was thrust out of the open window immediately above the street door.

"Who are you?" inquired the owner of the head in a voice which I recognised as that of Mr. Jellicoe.

"I am Inspector Badger, of the Criminal Investigation Department. I wish to see Mr. Arthur Jellicoe."
