T HAT night Tom and Huck were ready for their adventure. They hung about the neighborhood of the tavern until after nine, one watching the alley at a distance and the other the tavern door. Nobody entered the alley or left it; nobody resembling the Spaniard entered or left the tavern door. The night promised to be a fair one; so Tom went home with the understanding that if a considerable degree of darkness came on, Huck was to come and "maow," whereupon he would slip out and try the keys. But the night remained clear, and Huck closed his watch and retired to bed in an empty sugar hogshead about twelve.
Tuesday the boys had the same ill luck. Also Wednesday. But Thursday night promised better. Tom slipped out in good season with his aunt's old tin lantern, and a large towel to blindfold it with. He hid the lantern in Huck's sugar hogshead and the watch began. An hour before midnight the tavern closed up and its lights (the only ones thereabouts) were put out. No Spaniard had been seen. Nobody had entered or left the alley. Everything was auspicious. The blackness of darkness reigned, the perfect stillness was interrupted only by occasional mutterings of distant thunder.
