Someone Thinks The Word is French

Arthur was going to ride straight past the gate to Gemtree Caravan Park, Lavender could tell. He wasn't slowing down.

Stop, Arthur! said Lavender. There's something hanging on the fence.

Arthur stopped reluctantly.

He leaned towards the fence to get a closer look at what it was.

It was a lobster claw,  which had been used by someone as a clip to hold a note.

That lobster claw looks familiar, said Arthur. But what's it doing here?

Why don't you read the note, said Lavender.

There's two notes, said Arthur. The top one says: No Arthur! You must not think of Fossiquing! There is great danger for you here.

Wow! said Lavender. Danger! And did you say fosseeking?

No, fossiquing, said Arthur. As if someone thinks the word is French.

What does the underneath note say? asked Lavender.

It's torn, said Arthur, but this part says: To Arthur Rimbaud. If you are passing, please drop in to the office . Your friends have... then it's been torn off.

What are we going to do? asked Lavender.

What do you want to do? asked Arthur.

Are you scared of danger? asked Lavender.

Never in  my life, said Arthur.

Let's go fosseeking, said Lavender.
