‘Perhaps it is,’ said Fatty hopefully, and they all waited to see who came in.

But it was the vicar of Buckle! The children knew him quite well because he sometimes came to talk to them in their own church at Peterswood. He was a jolly, burly man and they liked him.

‘Can’t be him!’ said Fatty, disappointed. ‘Can’t possibly. Blow! We’re not a bit further on.’

‘Never mind - perhaps one of them will post a letter when they get out of the bus,’ said Pip. ‘We’ll hope for that. Maybe your sour-faced man will, Fatty. He looks the most likely of the lot. He may be telling lies when he says he is a stranger.’

The vicar talked to every one in the bus in his cheerful booming voice. The thin huddled man took no notice, and as the Vicar did not greet him, the children felt sure that he did not know him. So perhaps he was a stranger after all?

‘Soon be at Sheepsale now,’ said Fatty. ‘Golly, isn’t this a steep pull-up? They say it wanted eight horses to pull the coach up in the old days before motor-buses.’

The bus stopped under some big trees in Sheepsale. A babel of baaing, mooing, clucking and quacking came to every one’s ears. The market was in full swing!

‘Quick - hop out first!’ said Fatty to the others. ‘Stand by the post-office - and keep a close watch.’

The children hurried off. Miss Trimble nodded to them and walked away down a little lane. The Find-Outers spotted the post-office at once and went over to it. Fatty produced a letter, and began to stamp it carefully.

‘Don’t want Goon to wonder why we’re all standing about here,’ he murmured to tbe others. ‘May as well post this letter.’
