know a
place about here called Thexford Hall?"

Reggie surveyed him through half-closed eyes for a moment or two; then
he said:

"Now, I wonder why you asked that. If you were a friend of the people
there, or had business with them, you would have gone straight to the
house; instead of which, you come away from them, and ask the first
person you meet if he knows it. You will excuse me if I say that I scent
a mystery, Mr. Green. By the way, let me introduce myself--it's evident
that you have little of the detective in you, or you would have asked me
long ago. My name is Reginald Rex, a name with which you are probably
unacquainted, but which, I trust, will some day be known to the whole
world." He expressed the hope with bland simplicity.

"I am sure I hope it will," said Derrick. "I am sorry to disappoint you,
but there is no mystery in the case. I have come here to see a young
lady----"

"Miss Celia Grant," broke in Reggie, with an air of quiet triumph. "How

because your extremely candid countenance confirms my assertion."

"Upon my word, you're a most amusing young man," said Derrick, biting
his lip to prevent himself from colouring. "But I am bound to admit that

"Thanks to your candour. I will now place myself at your service," said
Reggie. "The young lady of whom we speak is a friend of mine--Mr. Green,
when I rise in the morning, and return to my virtuous couch at night, I
never fail to thank a beneficent Providence that I _can_ claim her as my
friend. Now, what you wish me to do, though you would rather die than
ask me, is to arrange a meeting between you and Miss Grant. I will do
so, without a moment's hesitation, because of Lavater."

"Because of _what_?" demanded Derrick, staring at him.

"Lavater, Mr. Green, is the author of the best-known work on
physiognomy, and physiognomy teaches us whom to trust and to distrust.
Informed by my knowledge of the science, I know that you are a man to be
trusted, and with this knowledge, I am prepared to befriend you. What
time this evening would you like to meet Miss Grant?"

Derrick regarded the strange youth with a mixture of amusement and
surprise, not untinctured by j
