'Why didn't you want him to see us?' he asked.

I did not reply till we reached the restaurant, and then I spoke to him gravely.

'Edgec.u.mbe,' I said, 'you were telling me just now that you intended to study the life of London, and that you meant to go to all sorts of places.'

'Yes,' he replied, 'what then?'

'Only this: take care of yourself, and don't let any one know what your plans are.'

'You must have a reason for saying that.'

'I have. You have told me more than once about your feeling that you and Springfield knew each other before you lost your memory.'

'Yes,' he replied, 'what then?'

'You say you had the feeling that Springfield was your enemy?'

'Yes, but I have no proof. Sometimes I am ashamed of harbouring such thoughts.'

'Self-preservation is the first law of life,' I said sententiously.

'Think, Edgec.u.mbe,--some one shot at you in France,--why? You say you don't know that you have a single enemy in the world. Then think of your recent illness.'

'But--but----' and I saw a look of wonder in his eyes.

'I only tell you to be careful,' I interposed. 'Don't let any one know your plans, and whatever you do, don't have anything to do with Springfield.'

The words had scarcely pa.s.sed my lips, when Springfield entered the room.

CHAPTER XXVI

'WHERE DOES G.o.d COME IN?'

Springfield glanced around as if looking for a table, and then seeing us, came up quickly and held out his hand.

'Awfully glad to see you,' he said heartily. 'I came to meet Buller, who I thought might be in your train. But as he wasn't there, and as I saw you two fellows come across here, I thought I'd follow you. Left them all well down in Devonshire?'

There was no suggestion of restraint or _arriere pensee_ in his tones; he spoke in the most natural way possible, and seemed to regard us as friends.

'I will join you, if I may,' he went on; 'I hate feeding alone. By the way, what are you fellows doing to-day? If you have nothing on hand, you might come on to my club.'

'I am afraid I can't,' I replied; 'I am fixed up. As for Edgec.u.mbe, he has to get back to duty.'

'I am at a loose end,' he went on. 'Of course there are hosts of men I know in London; all the same, it's a bit lonely here. I am staying at the----' and he mentioned a well-known military club. Then he looked at us, I thought, suspiciously.

'Was Miss Bolivick well when you left?' he asked. 'I--I am more than ordinarily interested in her'; and he glanced at Edgec.u.mbe as he spoke.

But Edgec.u.mbe's face did not move a muscle. Evidently he had taken my words to heart.

For a few seconds there was an awkward silence. Then he went on:

'Edgec.u.mbe, I feel I owe you an apology. It was only after I had left Devonshire that I fully realized what you had done for me. But for you, I should be a dead man, and I want to thank you. I am not much given to sentiment, I am not built that way, but believe me I am not ungrateful.

At the risk of your own life you saved mine, and I feel it deeply.'

He spoke so earnestly, and there was such a ring of sincerity in his voice, that I felt ashamed of myself for thinking of him suspiciously.

Still I could not forget the conversation which took place between him and St. Mabyn months ago, neither could I rid my mind of what had taken place since.

'If I can be of any service to you,' he continued, 'I should like to be,--I should really. I happen to know your colonel, and I'd like to see more of you. If you will let me know how you are fixed, I will look you up. You haven't any friends in London, have you?'

'No,' replied Edgec.u.mbe; 'no one excepting Lus...o...b...'

'And you don't know London?'

'I am afraid not. I have no memory of it, anyhow.'

'Then let me show you around. I could introduce you to a lot of men, too. You see, as an old Army man, I know the ropes.'

'It's awfully good of you, Springfield,' I said; 'but really I don't think Edgec.u.mbe is your sort, and it would be a shame to bother you.'

I felt awkward in saying this, because I spoke as though I were Edgec.u.mbe's guardian. To my surprise, however, Edgec.u.mbe eagerly accepted Springfield's offer.

'I'll let you know when I am free,' he said, 'and then, as you say, you can introduce me to some of the sights of London. But we must be off now, Lus...o...b.., I have some things to do.'

'What do you mean by that?' I said, when we were alone.

He laughed gaily. 'I am not such a simpleton as I look, old man. I am able to take care of myself.'

'But do you really mean to say that you are going to let him show you round London?'

'Why not? He knows London in a way which you and I don't.'

'But don't you feel that he is your enemy, and that he has some ulterior purpose in all this?'

'Of course I do, but it would be madness to let him know it. You needn't fear, my friend; I will be a match for him. As I told you down in Devonshire, there's going to be a battle royal between us. He looks upon me as a kind of fool, who can be easily duped. But I shan't be.'

It was some days after this before I heard anything of Edgec.u.mbe again.

As I think I have mentioned, I was on sick leave at the time, and after leaving him I went to see some friends in Oxford. While there I got a letter from him, saying that he had been taken ill almost immediately on his return to duty, and that a fortnight's leave had been granted to him.

He asked me when I should be returning to London, as he would like me to accompany him on his peregrinations through the City. I curtailed my visit to Oxford, so as to fall in with his plans, and found that he had taken up his quarters at a Y.M.C.A. Hut, which had been erected especially for the use of officers.

He was looking somewhat pale and hollow-eyed, as I entered a comfortably fitted-up lounge in the building.

'What's the matter with you?' I asked.

'Oh, nothing much. I had a sort of relapse after I got back to work, and the M.O. declared me unfit for duty. Evidently Colonel McClure wrote to him about me. He seems to think I was poisoned.'

'Did your M.O. tell you that?'

'Yes, and in his opinion the poison was not quite eradicated from my system. Funny, isn't it? Anyhow, they wouldn't let me work, and here I am. What we poor soldiers would do without the Y.M.C.A., Heaven only knows! Anyhow, it shows that Christianity is not quite dead in the country, for if ever there was a Christian body, the Y.M.C.A. is one.'
