t and took out a box.
"Here's a brand that looks like black Havana," he said. "And now, what
the dickens are you doing in that rig?"

"I've been taking a long ride in the country--on a motor cycle,"
answered Ashton-Kirk, crossing his shabbily clothed legs and striking
a match. "Any time you feel disinclined to face your meals, Pen, I
recommend you heartily to do the same. It is a greater bracer. At this
moment I really believe I could do complete justice to even the very
best culinary thoughts of our friend, Dr. Mercer."

Pendleton sat down and regarded his friend with questioning eyes.

"It wasn't to acquire an appetite that you made up this way. You've
been working."

Ashton-Kirk comfortably blew one smoke-ring through another before he
answered.

"Will you be surprised to hear that I have been following Miss Edyth
Vale on a little voyage to the neighborhood of Cordova?"

"Again!"

"But this time she did not pay a visit to Professor Locke. To-day the
favored one was Allan Morris."

"Morris! Then she knows where he is?"

"So it would seem."

anything from Professor Locke. And I replied to the effect that I
thought I had. Now," after a pause, devoted to the grateful smoke,
"when one sees a girl circumstanced as Miss Vale assuredly is in this
case, paying a secret visit to a man who is rather more than suspected
of the murder, what does one suppose?"

"That she is leagued with him, somehow," replied Pendleton,
reluctantly.

"Exactly. But on the other hand, when the same girl, upon sight of us,
rushes off and leaves the man to face us without giving him a hint as
to who we are, what does one suppose?"

But Pendleton rose gloomily and strode over to the window.

"I don't know," said he.

"One supposes," proceeded Ashton-Kirk, "that she has not much interest
in him." Here Pendleton faced about again. "If she had been leagued
with him, as you put it, you may be sure that she
