The next thing was to find out how to make himself known to this ally. He decided that the only way was to surprise him. He might get shot, but he trusted to his strength and agility against a man who was almost certainly wearied. When he had got him safe, explanations might follow.
Peter was now enjoying himself hugely. If only those infernal guns kept silent he would play out the game in the sober, decorous way he loved. So very delicately he began to wriggle forward to where the sound was.
The night was now as black as ink around him, and very quiet, too, except for soughings of the dying gale. The snow had drifted a little in the lee of the ruined walls, and Peter's progress was naturally very slow. He could not afford to dislodge one ounce of snow. Still the tinkling went on, now in greater volume. Peter was in terror lest it should cease before he got his man.
Presently his hand clutched at empty space. He was on the lip of the front trench. The sound was now a yard to his right, and with infinite care he shifted his position. Now the bell was just below him, and he felt the big rafter of the woodwork from which it had fallen. He felt something else - a stretch of wire fixed in the ground with the far end hanging in the void. That would be the spy's explanation if anyone heard the sound and came seeking the cause.
Somewhere in the darkness before him and below was the man, not a yard off. Peter remained very still, studying the situation. He could not see, but he could feel the presence, and he was trying to decide the relative position of the man and bell and their exact distance from him. The thing was not so easy as it looked, for if he jumped for where he believed the figure was, he might miss it and get a bullet in the stomach. A man who played so risky a game was probably handy with his firearms. Besides, if he should hit the bell, he would make a hideous row and alarm the whole front.
Fate suddenly gave him the right chance. The unseen figure stood up and moved a step, till his back was against the parados.
He actually brushed against Peter's elbow, who held his breath.
There is a catch that the Kaffirs have which would need several diagrams to explain. It is partly a neck hold, and partly a paralysing backward twist of the right arm, but if it is practised on a man from behind, it locks him as sure as if he were handcuffed. Peter slowly got his body raised and his knees drawn under him, and reached for his prey.
He got him. A head was pulled backward over the edge of the trench, and he felt in the air the motion of the left arm pawing feebly but unable to reach behind.
'Be still,' whispered Peter in German; 'I mean you no harm. We are friends of the same purpose. Do you speak German?'
'_Nein,' said a muffled voice.
'English?'
'Yes,' said the voice.
'Thank God,' said Peter. 'Then we can understand each other.
I've watched your notion of signalling, and a very good one it is.
I've got to get through to the Russian lines somehow before morning, and I want you to help me. I'm English - a kind of English, so we're on the same side. If I let go your neck, will you be good and talk reasonably?'
The voice assented. Peter let go, and in the same instant slipped to the side. The man wheeled round and flung out an arm but gripped vacancy.
'Steady, friend,' said Peter; 'you mustn't play tricks with me or I'll be angry.'
'Who are you? Who sent you?' asked the puzzled voice.
Peter had a happy thought. 'The Companions of the Rosy Hours,'
he said.
'Then are we friends indeed,' said the voice. 'Come out of the darkness, friend, and I will do you no harm. I am a good Turk, and I fought beside the English in Kordofan and learned their tongue. Ilive only to see the ruin of Enver, who has beggared my family and slain my twin brother. Therefore I serve the _Muscov _ghiaours.'
'I don't know what the Musky jaws are, but if you mean the Russians I'm with you. I've got news for them which will make Enver green. The question is, how I'm to get to them, and that is where you shall help me, my friend.'
'How?'
'By playing that little tune of yours again. Tell them to expect within the next half-hour a deserter with an important message.
Tell them, for God's sake, not to fire at anybody till they've made certain it isn't me.'
The man took the blunt end of his bayonet and squatted beside the bell. The first stroke brought out a clear, searching note which floated down the valley. He struck three notes at slow intervals.
For all the world, Peter said, he was like a telegraph operator calling up a station.
'Send the message in English,' said Peter.
'They may not understand it,' said the man.
'Then send it any way you like. I trust you, for we are brothers.'
After ten minutes the man ceased and listened. From far away came the sound of a trench-gong, the kind of thing they used on the Western Front to give the gas-alarm.
'They say they will be ready,' he said. 'I cannot take down messages in the darkness, but they have given me the signal which means "Consent".'
