Justice Lawrence Wargrave - Perfection!

Could my plan have gone any better? I accomplished my goal (with ease if I say so myself), and left no prints or evidence behind. It was not a very difficult plan to execute, mainly because of the alliance I had with Dr. Armstrong. I quickly got on Armstrong’s good side and it became simple from there on out. My death was easy to fake. Since Armstrong was the only person who could diagnose the deaths, it was easy to arrange the situation so that he would be the only person to come near me.
Unfortunately, I had to dispose of Armstrong as well as the others. I effortlessly lured him to a cliff, drew him near the edge, and nudged him off the cliff. I had a secret supply of Cyanides and Chloral Hydrate on the island and they helped with knocking off Marston, Mrs. Rogers, and Mrs. Brent. Neither Rogers nor MacArthur heard me come up behind them, and I simply cracked their skulls to eliminate them. I was all set in position for Blore to enter the house and effortlessly pushed the clock out the window. I had no involvement with Mr. Lombard’s death, I merely watched from one of the bedroom windows. I never knew how smart Mrs. Claythorne was, and I admit, she made a pretty slick move. When this was unfolding, I was also setting up a noose on the same hook that I hung the seaweed from, with a chair to kick over. I then waited in the corner of the room, covered by shadows and a curtain, and watched Mrs. Claythorne kick the chair away. The cleanup work was easy. I only had to move the chair up against the wall.
I then went into my room to set up the revolver. This was probably the hardest murder to set up, as the gun had to land right underneath my handkerchief. The gun was now in place. I had my fun, and now it was time for my exit…
