The Zeppelin's Passenger by E. Phillips Oppenheim

It seemed to the two women, brief though the period of actual silence was, that in those few seconds they jointly conceived definite and lasting impressions of the man who was to become, during the next few weeks, an object of the deepest concern to both of them. The intruder was slightly built, of little more than medium height, of dark complexion, with an almost imperceptible moustache of military pattern, black hair dishevelled with the wind, and eyes of almost peculiar brightness. He carried himself with an assurance which was somewhat remarkable considering the condition of his torn and mud stained clothes, the very quality of which was almost undistinguishable. They both, curiously enough, formed the same instinctive conviction that, notwithstanding his tramplike appearance and his burglarious entrance, this was not a person to be greatly feared.
