ly was.

He therefore watched him narrowly and succeeded in getting one glance
from his eye. It was enough. The man was commonplace,--commonplace in
feature, dress and manner, but his eye gave him away. There was nothing
commonplace in that. It was an eye to beware of.

He had taken in Sweetwater as he passed, but Sweetwater was of a
commonplace type, too, and woke no corresponding dread in the other's
mind; for he went whistling into the store, from which he presently
reissued with a bundle of mail in his hand. The detective's first
instinct was to take him into custody as a suspect much wanted by the
New York police; but reason assured him that he not only had no
warrant for this, but that he would better serve the ends of justice by
following out his present task of bringing this man and the Englishman
together and watching the result. But how, with the conditions laid
on him by Mr. Grey, was this to be done? He knew nothing of the man's
circumstances or of his position in the town. How, then, go to work to
secure his cooperation in a scheme possibly as mysterious to him as it
was to himself? He could stop this stranger in mid-street, with some
plausible excuse, but it did not follow that he would succeed in luring
him to the hotel where Mr. Grey could see him. Wellgood, or, as he
believed, Sears, knew too much of life to be beguiled by any open
clap-trap, and Sweetwater was obliged to see him drive off without
having made the least advance in the purpose engrossing him.

But that was nothing. He had all the evening before him, and reentering
the store, he took up his stand near the sugar barrel. He had perceived
that in the pauses of weighing and tasting, Dick talked; if he were
guided with suitable discretion, why should he not talk of Wellgood?

He was guided, and he did talk and to some effect. That is, he gave
information of the man which surprised Sweetwater. If in the past and in
New York he had been known as a waiter, or should I say steward, he was
known here as a manufacturer of patent medicine designed to rejuvenate
the human race. He had not been long in town and was somewhat of a
stranger yet, but he wouldn't be so long. He was going to make things
hum, he was. Money for this, money for that, a horse where another man
would walk, and mail--well, that alone would make this post-office worth
while. Then the drugs ordered by wholesale. Those boxes over there were
his, ready to be carted out to his manufa
