is pacific and rather gloomy
exterior, could be counted on to be extremely dangerous.

In a situation where any man might prove to be his hidden enemy, Renwick
was learning to be wary. And so upon his guard for any movement of
hostility, he sat bolt upright and smoked his cigarette, puffing it
indolently into the face of his solemn companion. Beyond the first
greeting, no words passed between them, and the Englishman, more at his
ease, looked out of the window at the low marshlands along the river and
planned the business which brought him. Day came swiftly, and before the
train reached the city the sun was up in smiling splendor, melting the
pale fogbanks of the Danube valley beneath its golden glow.

At the Westbahnhof, Renwick got down, and bag in hand made his way to

He was no sooner comfortably seated in his compartment and

opportunity for sleep, when the door was thrown open and his tall
companion of the early morning solemnly entered. Renwick did not know
whether to be surprised or angry, and finished by being both, glancing
at the intruder through his monocle in a manner distinctly offensive.
But the tall man if aware of the Englishman's antagonism gave no sign of
it, clasping his cotton umbrella with large bony hands and gazing
gloomily at the passing landscape.

An accidental meeting of two travelers bound in the same direction?
Perhaps. But there was too much at stake for Renwick to be willing to
take chances, and yet he could not
