Can someone please help ASAP!!!!!

Read the excerpt from the novel Treasure Island and answer the question that follows.

Every day when he came back from his stroll he would ask if any seafaring men had gone by along the road. At first we thought it was the want of company of his own kind that made him ask this question, but at last we began to see he was desirous to avoid them. When a seaman did put up at the Admiral Benbow (as now and then some did, making by the coast road for Bristol) he would look in at him through the curtained door before he entered the parlour; and he was always sure to be as silent as a mouse when any such was present.

What is the tone of the passage?
Playful
Sad
Sarcastic
Fearful
