awson--our remarkable Dawson of the double life in the two
compartments, professional and private, which never are allowed to
overlap--Dawson is an instrument of war. We do not like using gas or
liquid fire, but we are compelled to use them. We do not like
espionage, but we must employ it. As one who loves this fair land of
England beyond everything in the world, and as one who would do
anything, risk anything, and suffer anything to shield her from the
filthy Germans, I rejoice that she has in her service such supremely
efficient guardians as this most wickedly unscrupulous Dawson. There
is, at any rate, not a trace of our English muddle about him."

"Ours is a righteous cause," cried poor Cary desperately. "We are
fighting for right against wrong, for defence against aggression, for
civilisation against utter barbarism. We are by instinct clean
fighters. If in the stress of conflict we stoop to foul methods, can
we ever wash away the filth of them from our souls? We shall stand
before the world nakedly confessed as the nation of hypocrites we have
always been declared to be."

"Cary," I said, "you make me tired. We cannot be too thankful that we
possess Dawsons to counterplot against the Germans, and that
personally we are in no way responsible for the morality of their
methods. Come off the roof and get back to this most interesting
affair of the _Antinous_. I presume one of Dawson's men was working,
unknown to his fellows, with the care and maintenance party, and
another, equally unknown, with the engineers who were busy upon the
gearing of the turbines. Many of the regular ship's officers and men
would also have been on board. Had our remarkable friend his agents
among them too? Everything is possible with Dawson; I should not be
surprised to hear that he had police officers in the Fleet flagship."

"You are almost right. One of his men, a temporary petty officer of
R.N.V.R., was certainly on board, and he tells me that down in the
engine room was another--a civilian fitter. They were both first-class
men. The electric wires, as you know, are carried about the ship under
the deck beams, where they are accessible for examination and repairs.
They are coiled in cables from which wires are led to the switch room,
and thence to all parts of the ship. There are thousands of wires, and
no one who did not know intimately their purpose and disposition could
venture to tamper with them, for great numbers are always in use
