What did Jim think and feel about the stranger who came to the inn and enquired about the seaman?

Jim felt "uneasy and alarmed" with the stranger, and admits that he "puzzled [him]".

Explanation:

Robert Louis Stevenson's "Treasure Island" revolves around the protagonist Jim Hawkins' adventures and his search for a treasure. The story is set with characters like pirates, journeys by ship, and the usual interesting story of an evil pirate and the fight to get to a buried treasure.

Jim Hawkins recalls how he first met "Black Dog", the former shipmate of "Captain" Bill, a guest at their inn "The Admiral Benbow". Jim recounts how the new guy was "a pale, tallowy creature, wanting two fingers of the left hand, and though he wore a cutlass, he did not look much like a fighter." He also went further to admit that "... this one puzzled [him]", and the longer he was in the company of the stranger, the more "uneasy and alarmed" Jim became.
