ou became an heiress. No one can say that I marry you for
anything save your own sweet self. And I am doubly glad that I am to
marry you and save you from all the disagreeable things which might have
occurred had you not been engaged to me."

"I know, Paul. I am so young and inexperienced."

"You are an angel," said he, embracing her. "But there's one thing we
must do"--and his voice became graver--"we must see Pash and offer a
reward for the discovery of the person who killed your father."

"But Mr. Pash said let sleeping dogs lie," objected Sylvia.

"I know he did, but out of natural affection, little as your poor father
loved you, we must stir up this particular dog. I suggest that we offer
a reward of five hundred pounds."

"To whom?" asked Sylvia, thoroughly agreeing.

"To anyone who can find the murderer. I think myself, that Hurd will be
the man to gain the money. Apart from any reward he has to act on behalf

_alias_ Aaron Norman, something might come to light relative to the
man's early life. Once that was known, the clue might be obtained. Then
the truth would surely be discovered. He explained this to Hurd.

"I think you're right, Mr. Beecot," said the detective, in his genial
way, and looking as brown as a coffee bean. "I have made inquiries from
the two servants, and from the neighbors, and from what customers I
could find. Aaron Norman certainly lived a very quiet and respectable
life here. But Lemuel Krill may have lived a very different one, and the
mere fact that he changed his name shows that he had something to
conceal. When we learn that something we may arrive at the motive for
the murder, and, given that, the assassin may be caught."

"The assassin!" echoed Paul. "Then you think there w
