Six o’clock struck on the bells of the church that was so conveniently near to Mr. Utterson’s dwelling, and still he was digging
at the problem. Hitherto it had touched him on the intellectual side alone; but now his imagination also was engaged, or rather enslaved; and as he lay and tossed in the gross darkness of the night and the curtained room, Mr. Enfield’s tale went by before his mind in a scroll of lighted pictures. He would be aware of the great field of lamps of a nocturnal city; then of the figure of a man walking swiftly; then of a child running from the doctor’s . . . What is the mood of the excerpt?
The mood of this excerpt is trouble. The words enslaved, tossed, and gross darkness help show the mood and show that the man is troubled. Hope this helps you :)
