“Have we arrived? I never thought we should!”

“Oh, I thought we’d get to London all right. If there’s going to be any fun, now is when it will begin. Quick, get out. We’ll nip into a taxi.”

In another minute they were passing the barrier, had paid the necessary fares, and were stepping into a taxi.

“King’s Cross,” directed Tuppence. Then she gave a jump. A man looked in at the window, just as they started. She was almost certain it was the same man who had got into the carriage next to them. She had a horrible feeling of being slowly hemmed in on every side.

“You see,” she explained to Jane, “if they think we’re going to Sir James, this will put them off the scent. Now they’ll imagine we’re going to Mr. Carter. His country place is north of London somewhere.”

Crossing Holborn there was a block, and the taxi was held up. This was what Tuppence had been waiting for.
