It all sounded extremely likely, but somehow Larry thought it was too likely. ‘Couldn’t the person go on a bike?’ he said.
‘Well - he could - but think of that awful hill up to Sheepsale,’ said Fatty. ‘Nobody in their senses would bike there when a bus goes.’
‘No - I suppose not,’ said Larry. ‘Well - I don’t see that all this gets us much farther, Fatty. All we’ve found out is that more people than Gladys and Molly have had these letters - and that they all come from Sheepsale and are posted at or before 11.45 - and that possibly the letter-writer may catch the 10.15 bus from Peterswood.’
‘All we’ve found out!’ said Fatty. ‘Gosh, I think we’ve discovered an enormous lot. Don’t you realize that we’re really on the track now - the track of this beastly letter-writer. Why, if we want to, we can go and see him - or her - on Monday morning!’
The others stared at Fatty, puzzled.
‘We’ve only got to catch that 10.15 bus!’ said Fatty. ‘See? The letter-writer is sure to be on it. Can’t we discover who it is just by looking at their faces? I bet I can!’
‘Oh, Fatty!’ said Bets, full of admiration. ‘Of course - we’ll catch that bus. But, oh dear, I should never be able to tell the right person, never. Will you really be able to spot who it is?’
‘Well, I’ll have a jolly good try,’ said Fatty, ‘And now I’d better take these letters back, I think. But first of all I want to make a tracing of some of these sentences - especially words like “PETERSWOOD” that occur in each address - in case I come across somebody who prints their words in just that way.’
‘People don’t print words, though - they write them,’ said Daisy. But Fatty took no notice. He carefully traced a few of the words, one of them being ‘PETERSWOOD.’ He put the slip into his wallet. Then he snapped the bit of elastic round the package and stood up.
‘How are you going to get the letters back without being seen?’ asked Larry.
