The lad looked terrified as I hauled him up the stairs. In fact, his face blanched even paler as I presented him before Sherlock and the doctor, both whose faces were clouded in rage.
"I'm seeing you after sometime" the doctor almost spat his words out "David Lambert."
The lad's face became even paler. "Then, are you…are you…John Watson?"
"He is" I have seldom heard Sherlock sound so cold "And now, Mr. Lambert, let us-"
"I'm-I'm not David!"
The lad's terrified exclamation had an unusual effect. Sherlock leaned back, a sardonic smile m his lips. The doctor merely looked disgusted.
"Then who are you, if not David Lambert?"
"My n-name is Joseph, s-sir. Joseph Lambert, David's brother."
