Without the least exaggeration, I must acknowledge to having been during my career in some very uncomfortable predicaments while grovelling through the vicissitudes of life’s various phases, and a strong resolution, which I have always held sacred, has been, never to take a life without giving the person a chance for his own; therefore, self-defence or being in action with the enemy could be my only palliation. This night, however, presented cause for exception to this rule. The corner of a large steam-engineering building hid from view the man whose shadow played in grotesque evolutions on the pier, and it was impossible to see him without uncovering myself to his gaze, but there lurked the shadow of every move cast vividly before my keen-set eyes. As I quietly knelt in seclusion surrounded by the densest gloom, meditating as to how I might take the object alive, positively realizing that he was well armed, from my previous experience with river thieves, I saw the shadow portray a man drawing a gun and examining it closely, the shadow indicating that he was either trying the trigger or testing the T block of an automatic pistol. It dawned on me that my duty bade me to halt this man, and, if in any way he attempted to evade me, to kill him. I had the narrow neck of the channel covered, and it was my intention, if he attempted to shove off in a boat with any copper, to halt him, and, if he ignored my command, to fire. However, not seeing the shadow disappear for even an instant aroused my suspicion, as to load the copper in the boat in any shape or manner it would have been necessary to pass on the opposite side of an old obsolete sentry-box, thereby obliterating even the semblance of a shadow. I was cognizant of the fact that had I aroused the guard they would send out the steam-launch to cover the exit, and, if the man attempted to escape, fire on him, which I wished to prevent.
