‘I can’t believe it,’ murmured Jane. ‘He seemed so splendid.’
‘The real Julius Hersheimmer was a splendid fellow! And Mr Brown is a consummate actor. But ask Miss Tuppence if she also has not had her suspicions.’
Jane turned mutely to Tuppence. The latter nodded.
‘I didn’t want to say it, Jane – I knew it would hurt you. And, after all, I couldn’t be sure. I still don’t understand why, if he’s Mr Brown, he rescued us.’
‘Was it Julius Hersheimmer who helped you to escape?’
Tuppence recounted to Sir James the exciting events of the evening, ending up: ‘But I can’t see why!’
‘Can’t you? I can. So can young Beresford, by his actions. As a last hope Jane Finn was to be allowed to escape – and the escape must be managed so that she harbours no suspicions of its being a put-up job. They’re not averse to young Beresford’s being in the neighbourhood, and, if necessary, communicating with you. They’ll take care to get him out of the way at the right minute. Then Julius Hersheimmer dashes up and rescues you in true melodramatic style. Bullets fly – but don’t hit anybody. What would have happened next? You would have driven straight to the house in Soho and secured the document which Miss Finn would probably have entrusted to her cousin’s keeping. Or, if he conducted the search, he would have pretended to find the hiding-place already rifled. He would have had a dozen ways of dealing with the situation, but the result would have been the same. And I rather fancy some accident would have happened to both of you. You see, you know rather an inconvenient amount. That’s a rough outline. I admit I was caught napping; but somebody else wasn’t.’
‘Tommy,’ said Tuppence softly.
‘Yes. Evidently when the right moment came to get rid of him – he was too sharp for them. All the same, I’m not too easy in my mind about him.’
‘Why?’
‘Because Julius Hersheimmer is Mr Brown,’ said Sir James dryly. ‘And it takes more than one man and a revolver to hold up Mr Brown …’
Tuppence paled a little.
‘What can we do?’
‘Nothing until we’ve been to the house in Soho. If Beresford has still got the upper hand, there’s nothing to fear. If otherwise, our enemy will come to find us, and he will not find us unprepared!’ From a drawer in the desk, he took a Service revolver, and placed it in his coat pocket.
‘Now we’re ready. I know better than even to suggest going without you, Miss Tuppence –’
‘I should think so indeed!’
‘But I do suggest that Miss Finn should remain here. She will be perfectly safe, and I am afraid she is absolutely worn out with all she has been through.’
But to Tuppence’s surprise Jane shook her head.
‘No. I guess I’m going too. Those papers were my trust. I must go through with this business to the end. I’m heaps better now anyway.’
Sir James’s car was ordered round. During the short drive Tuppence’s heart beat tumultuously. In spite of momentary qualms of uneasiness respecting Tommy, she could not but feel exultation. They were going to win!
The car drew up at the corner of the square and they got out. Sir James went up to a plain-clothes man who was on duty with several others, and spoke to him. Then he rejoined the girls.
‘No one has gone into the house so far. It is being watched at the back as well, so they are quite sure of that. Anyone who attempts to enter after we have done so will be arrested immediately. Shall we go in?’
A policeman produced a key. They all knew Sir James well. They had also had orders respecting Tuppence. Only the third member of the party was unknown to them. The three entered the house, pulling the door to behind them. Slowly they mounted the rickety stairs. At the top was the ragged curtain hiding the recess where Tommy had hidden that day. Tuppence had heard the story from Jane in her character of ‘Annette’. She looked at the tattered velvet with interest. Even now she could almost swear it moved – as though someone was behind it. So strong was the illusion that she almost fancied she could make out the outline of a form … Supposing Mr Brown – Julius – was there waiting …
Impossible of course! Yet she almost went back to put the curtain aside and make sure …
Now they were entering the prison room. No place for anyone to hide here, thought Tuppence, with a sigh of relief, then chided herself indignantly. She must not give way to this foolish fancying – this curious insistent feeling that Mr Brown was in the house … Hark! what was that? A stealthy footstep on the stairs? There was someone in the house! Absurd! She was becoming hysterical.
Jane had gone straight to the picture of Marguerite. She unhooked it with a steady hand. The dust lay thick upon it, and festoons of cobwebs lay between it and the wall. Sir James handed her a pocket-knife, and she stripped away the brown paper from the back … The advertisement page of a magazine fell out. Jane picked it up. Holding apart the frayed inner edges she extracted two thin sheets covered with writing!
No dummy this time! The real thing!
‘We’ve got it,’ said Tuppence. ‘At last …’
The moment was almost breathless in its emotion. Forgotten the faint creakings, the imagined noises of a minute ago. None of them had eyes for anything but what Jane held in her hand.
Sir James took it, and scrutinized it attentively.
‘Yes,’ he said quietly, ‘this is the ill-fated draft treaty!’
‘We’ve succeeded,’ said Tuppence. There was awe and an almost wondering unbelief in her voice.
Sir James echoed her words as he folded the paper carefully and put it away in his pocket-book, then he looked curiously round the dingy room.
‘It was here that your young friend was confined for so long, was it not?’ he said. ‘A truly sinister room. You notice the absence of windows, and the thickness of the close-fitting door. Whatever took place here would never be heard by the outside world.’
Tuppence shivered. His words woke a vague alarm in her. What if there was someone concealed in the house? Someone who might bar that door on them, and leave them to die like rats in a trap? Then she realized the absurdity of her thought. The house was surrounded by police who, if they failed to reappear, would not hesitate to break in and make a thorough search. She smiled at her own foolishness – then looked up with a start to find Sir James watching her. He gave her an emphatic little nod.
‘Quite right, Miss Tuppence. You scent danger. So do I. So does Miss Finn.’
‘Yes,’ admitted Jane. ‘It’s absurd – but I can’t help it.’
Sir James nodded again.
‘You feel – as we all feel – the presence of Mr Brown.
Yes’
