said nothing to me about any of this, and I had been looking forward
to our dinner this evening and to the company that I hoped would be 
there. I could not understand why Holmes wished me to go with him to
London, so that we were both absent at a moment which he himself
declared to be critical, but he would not enlighten me, and I knew that
I would get nothing from him, until he wished to tell me. There was
nothing for it but implicit obedience.
We drove to Coombe Tracey, a journey of a couple of hours, leaving the
rueful baronet behind. Cartwright was waiting at the station for orders.
Holmes told him to take the next train to London, and then to wire Sir
Henry, in Holme's name, to ask him to look for a pocket book which
Holmes had dropped at Baskerville Hall. Holmes then picked up a wire
himself in the station office. It was from Scotland Yard.
