Outside the house beyond a flagged terrace the lawn fell away, white in the moonshine, to the edge of the stream, which here had expanded into a miniature lake. By the water's edge was a little formal garden with grey stone parapets which now gleamed like dusky marble. Great wafts of scent rose from it, for the lilacs were scarcely over and the may was in full blossom. Out from the shade of it came suddenly a voice like a nightingale.
It was singing the old song 'Cherry Ripe', a common enough thing which I had chiefly known from barrel-organs. But heard in the scented moonlight it seemed to hold all the lingering magic of an elder England and of this hallowed countryside. I stepped inside the garden bounds and saw the head of the girl Mary.
She was conscious of my presence, for she turned towards me.
'I was coming to look for you,' she said, 'now that the house is quiet. I have something to say to you, General Hannay.'
She knew my name and must be somehow in the business. The thought entranced me.
'Thank God I can speak to you freely,' I cried. 'Who and what are you - living in that house in that kind of company?'
'My good aunts!' She laughed softly. 'They talk a great deal about their souls, but they really mean their nerves. Why, they are what you call my camouflage, and a very good one too.'
'And that cadaverous young prig?'
'Poor Launcelot! Yes - camouflage too - perhaps something a little more. You must not judge him too harshly.'
'But ... but -' I did not know how to put it, and stammered in my eagerness. 'How can I tell that you are the right person for me to speak to? You see I am under orders, and I have got none about you.'
'I will give You Proof,' she said. 'Three days ago Sir Walter Bullivant and Mr Macgillivray told you to come here tonight and to wait here for further instructions. You met them in the little smoking-room at the back of the Rota Club. You were bidden take the name of Cornelius Brand, and turn yourself from a successful general into a pacifist South African engineer. Is that correct?'
'Perfectly.'
'You have been restless all evening looking for the messenger to give you these instructions. Set your mind at ease. No messenger is coming. You will get your orders from me.'
'I could not take them from a more welcome source,' I said.
'Very prettily put. If you want further credentials I can tell you much about your own doings in the past three years. I can explain to you who don't need the explanation, every step in the business of the Black Stone. I think I could draw a pretty accurate map of your journey to Erzerum. You have a letter from Peter Pienaar in your pocket - I can tell you its contents. Are you willing to trust me?'
'With all my heart,' I said.
'Good. Then my first order will try you pretty hard. For I have no orders to give you except to bid you go and steep yourself in a particular kind of life. Your first duty is to get "atmosphere", as your friend Peter used to say. Oh, I will tell you where to go and how to behave. But I can't bid you do anything, only live idly with open eyes and ears till you have got the "feel" of the situation.'
She stopped and laid a hand on my arm.
'It won't be easy. It would madden me, and it will be a far heavier burden for a man like you. You have got to sink down deep into the life of the half-baked, the people whom this war hasn't touched or has touched in the wrong way, the people who split hairs all day and are engrossed in what you and I would call selfish little fads. Yes. People like my aunts and Launcelot, only for the most part in a different social grade. You won't live in an old manor like this, but among gimcrack little "arty" houses. You will hear everything you regard as sacred laughed at and condemned, and every kind of nauseous folly acclaimed, and you must hold your tongue and pretend to agree. You will have nothing in the world to do except to let the life soak into you, and, as I have said, keep your eyes and ears open.'
'But you must give me some clue as to what I should be looking for?'
'My orders are to give you none. Our chiefs - yours and mine -want you to go where you are going without any kind of _parti _pris.
Remember we are still in the intelligence stage of the affair. The time hasn't yet come for a plan of campaign, and still less for action.'
'Tell me one thing,' I said. 'Is it a really big thing we're after?'
'A - really - big - thing,' she said slowly and very gravely. 'You and I and some hundred others are hunting the most dangerous man in all the world. Till we succeed everything that Britain does is crippled. If we fail or succeed too late the Allies may never win the victory which is their right. I will tell you one thing to cheer you.
It is in some sort a race against time, so your purgatory won't endure too long.'
I was bound to obey, and she knew it, for she took my willingness for granted.
From a little gold satchel she selected a tiny box, and opening it extracted a thing like a purple wafer with a white St Andrew's Cross on it.
'What kind of watch have you? Ah, a hunter. Paste that inside the lid. Some day you may be called on to show it ... One other thing. Buy tomorrow a copy of the _Pilgrim's _Progress and get it by heart. You will receive letters and messages some day and the style of our friends is apt to be reminiscent of John Bunyan ... The car will be at the door tomorrow to catch the ten-thirty, and I will give you the address of the rooms that have been taken for you ...
Beyond that I have nothing to say, except to beg you to play the part well and keep your temper. You behaved very nicely at dinner.'
I asked one last question as we said good night in the hall. 'Shall I see you again?'
'Soon, and often,' was the answer. 'Remember we are colleagues.'
I went upstairs feeling extraordinarily comforted. I had a perfectly beastly time ahead of me, but now it was all glorified and coloured with the thought of the girl who had sung 'Cherry Ripe' in the garden. I commended the wisdom of that old serpent Bullivant in the choice of his intermediary, for I'm hanged if I would have taken such orders from anyone else.
