Narrative:

I departed ZZZ on a 135 charter flight with 2 passengers at xa:30. After landing and clearing customs I used up almost all daylight left; however a cold front had just passed and there was a lingering twilight with unlimited ceiling. This gave me a false sense of security as I thought it would last the 46 miles I had back to my destination. By the time I returned back to ZZZ it was dark and although its waterway was visible by the surrounding lights I had to execute a glassy water landing. The fact that I was able to execute a safe landing does not diminish the fact that I succumbed to a bad case of 'get-home-it is.' and that although I could see that waterway I could not see the possible obstructions floating just beneath the surface! (As I have on previous occasions during the day).
