    That morning， we noticed a cab following Sir Henry and Dr．Mortimer in London． But who？

We went to Sir Henry's hotel． Holmes asked Dr． Mortimer if anyone with a black beard lived in or near Baskerville Hall．

"Yes，" said Dr．Mortimer，"Barrymore．"

"We must send a telegram to check whether Barrymore is in London or at Baskerville Hall，"said Holmes．

Sir Henry said he wanted to go to Baskerville Hall．

"OK"， said Holmes． "But you mustn't go alone． Watson can go with you．"

Sir Henry and I agreed to take the 10：30 train on Saturday．

Holmes thought deeply on the way home： the story of the Hound， Sir Charles's death， the strange letter， the missing boot and the black-bearded man． He sat in his room all afternoon， smoking and thinking．

Just before dinner， a telegram arrived． It said，"Barrymore is at Baskerville Hall．"

"That becomes a dead end， Watson． We will have to look for another way to go forward．

Just then the door bell rang． It was the cab driver who drove the man with the black beard． "I got a message that you are asking for me"， he said． "I've never had a complaint． I came here to ask you what you had against me! "

"No， no，" said Holmes． "Instead， I'll give you money if you tell me about the man in your cab this morning． He watched this house at 10：00 and then told you to follow the two gentlemen．"

The driver looked surprised and then answered，"The man said he was a detective（侦探） and that I shouldn't tell anyone about him． "

"It's serious， my friend， and you may be in trouble if you refuse to answer．" "His name，" said the driver， "was Sherlock Holmes．"

I'd never seen Holmes more surprised． Then he laughed． "He scored against me that time， Watson．"

The driver told us everything he knew． Holmes gave him the money and sent him away． "This is a dangerous enemy （敌人）， Watson．"
