'It's absolutely essential that you get them perfect,' he said. 'We have a game every day next week, you know that. And we've got to eat.'
'What is this?' my wife whispered. 'What on earth is it?'
'Shhh!' I said. 'Listen!'
'All right,' the man's voice was saying. 'Now we'll start from the beginning. Ready?'
'Oh Henry, please!' She sounded very near to tears.
'Come on, Sally. Pull yourself together.'
Then, in a quite different voice, the one we had been used to hearing in the living-room, Henry Snape said, 'One club.' I noticed that there was a curious lilting emphasis on the word 'one', the first part of the word drawn out long.
'Ace queen of clubs,' the girl replied wearily. 'King jack of spades. No hearts, and ace jack of diamonds.'
'And how many cards to each suit? Watch my finger positions carefully.'
'You said we could miss those.'
'Well - if you're quite sure you know them?'
'Yes, I know them.'
A pause, then 'A club.'
'King jack of clubs,' the girl recited. 'Ace of spades. Queen jack of hearts, and ace queen of diamonds.'
Another pause, then 'I'll say one club.'
'Ace king of clubs ...'
'My heavens alive!' I cried. 'It's a bidding code! They show every card in the hand!'
'Arthur, it couldn't be!'
'It's like those men who go into the audience and borrow something from you and there's a girl blindfold on the stage, and from the way he phrases the question she can tell him exactly what it is - even a railway ticket, and what station it's from.'
'It's impossible!'
'Not at all. But it's tremendous hard work to learn. Listen to them.'
'I'll go one heart,' the man's voice was saying.
'King queen ten of hearts. Ace jack of spades. No diamonds. Queen jack of clubs ...'
'And you see,' I said, 'he tells her the number of cards he has in each suit by the position of his fingers.'
'How?'
'I don't know. You heard him saying about it.'
'My God, Arthur! Are you sure that's what they're doing?'
'I'm afraid so.' I watched her as she walked quickly over to the side of the bed to fetch a cigarette. She lit it with her back to me and then swung round, blowing the smoke up at the ceiling in a thin stream. I knew we were going to have to do something about this, but I wasn't quite sure what because we couldn't possibly accuse them without revealing the source of our information. I waited for my wife's decision.
'Why, Arthur,' she said slowly, blowing out clouds of smoke. 'Why, this is a marvellous idea. D'you think we could learn to do it?'
'What!'
