and when they came together, invariably there was
trouble.

Kilsip was tall and slender; Gorby was short and stout. Kilsip looked
clever; Gorby wore a smile of self-satisfaction; which alone was
sufficient to prevent his doing so. Yet, singularly enough, it was this
very smile that proved most useful to Gorby in the pursuit of his
calling. It enabled him to come at information where his sharp-looking
colleague might try in vain. The hearts of all went forth to Gorby's
sweet smile and insinuating manner. But when Kilsip appeared people
were wont to shut up, and to retire promptly, like alarmed snails,
within their shells. Gorby gave the lie direct to those who hold that
the face is ever the index to the mind. Kilsip, on the other hand, with
his hawk-like countenance, his brilliant black eyes, hooked nose, and
small thin-lipped mouth, endorsed the theory. His complexion was quite
colourless, and his hair was jet black. Altogether, he could not be
called fair to look upon. His craft and cunning were of the snake-like
order. So long as he conducted his enquiries in secret he was generally
successful; but once let him appear personally on the scene, and
failure was assured to him. Thus, while Kilsip passed as the cleverer,
Gorby was invariably the more successful--at all events, ostensibly.

When, therefore, this hansom cab murder case was put into Gorby's
hands, the soul of Kilsip was smitten with envy, and when Fitzgerald
was arrested, and all the evidence collected by Gorby seemed to point
so conclusively to his guilt, Kilsip writhed in secret over the triumph
of his enemy. Though he would only have been too glad to say that Gorby
had got hold of the wrong man, yet the evidence was so conclusive that
such a thought never entered his head until he received a note from Mr.
Calton, asking him to call at his office that evening at eight o'clock,
with reference to the murder.

Kilsip knew that Calton was counsel for the prisoner. He guessed that
he was wanted to follow up a clue. And he determined to devote himself
to whatever Calton might require of him, if only to prove Gorby to be
wrong. So pleased was he at the mere possibility of triumphing over his
rival, that on casually meeting him, he stopped and invited him to
drink.

The primary effect of his sudden and unusual hospitality was to arouse
all Gorby's suspicions; but on second thoughts, deeming himself quite a
match for Kilsip, both mentally and physically, Gorby
