"Hallo, Nash! have you found anything? have you found out who his man of business was?"
Mr. Nash glanced up from the papers he was studying; if he was a little startled by the doctor's unheralded appearance he gave no sign of it.
"I haven't discovered his man of business; but I have found something."
"You haven't come upon anything which shows who it was he generally employed; I understand you've been here some time."
Mr. Nash shook his head.
"I don't know how long I have been here, but I've come on nothing which shows that he ever employed any one at all."
"He must have employed some one."
The other shrugged his shoulders.
"I've gone through a good many of his papers; I've not hit on one which suggests it."
"You said you'd found something; what is it?"
