"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.
"Quick," she whispered. "Open the right-hand door!"
The two girls stepped out into the traffic. Two minutes later they were seated in another taxi and were retracing their steps, this time direct to Carlton House Terrace.
"There," said Tuppence, with great satisfaction, "this ought to do them. I can't help thinking that I'm really rather clever! How that other taxi man will swear! But I took his number, and I'll send him a postal order to-morrow, so that he won't lose by it if he happens to be genuine. What's this thing swervingOh!"
There was a grinding noise and a bump. Another taxi had collided with them.
In a flash Tuppence was out on the pavement. A policeman was approaching. Before he arrived Tuppence had handed the driver five shillings, and she and Jane had merged themselves in the crowd.
"It's only a step or two now," said Tuppence breathlessly. The accident had taken place in Trafalgar Square.
"Do you think the collision was an accident, or done deliberately?"
