Theory:

     “But starvation!”
 
     “That may be a bit flowery, as the saying is— but I know myself he was sitting over his boots day and night, to the very last you see, I used to watch him. Never gave himself time to eat; never had a penny in the house. All went in rent and leather. How he lived so long I don’t know. He regularly let his fire go out. He was a character. But he made good boots.”
 
     “Yes,” I said, “he made good boots.”
Explanation:
 
Mr. Gessler's death was still a mystery to the author. The author still couldn't understand how starvation can be a cause for Mr. Gessler's death.

The Englishman then proceeded to explain the author. He informed the author that while stating Gessler died of starvation seemed a little fancy and exaggerated, it was the truth.

The man said he used to keep track of his acts from dawn to night, right up until the last boot he put on his last day. The bootmaker (Gessler) was a poor man who never ate and had no money. He'd put all of his money on rent and leather, but not food. He also added that seeing someone so old go so long without eating astounded him. At last, Gessler's passion for his art took away his life. Though Gessler had a unique personality, he created excellent boots. 'Yes, he made good boots,' the author replied with a heavy heart.
