Can you hear me? Yes. Can you get Sunday afternoon off? Yes. Then listen carefully. Go to Paddington Station——turn left outside the station,and you come to a gate with the top bar missing; a path across afield; a grass-grown lane; a track between bushes; Stay on left and you come to a dead tree with moss on it. Can you remember all that? Yes. You turn left, then right, then left again. And the gate’s got no top bar. Yes. What time? About fifteen. You may have to wait. I’ll get there by another way. Are you sure you remember everything? Yes. Then get away from me as quick as you can.
