The Staircase With Thirteen and a Half Steps
The stairs in Ravi's new house had thirteen steps. He counted them each night on the way to bed. But on the first stormy evening, he counted fourteen, and the fourteenth was only half as tall as the rest.
The half step was at the very bottom, tucked under the first one. When Ravi stepped on it, it gave a soft chime, like a spoon on a glass. The wall beside it slid open a crack.
Behind it was a closet the size of a bookshelf. It held a lantern, a ball of yarn, and a small note. The note said, "Whoever finds the half step may borrow the lantern, but must put it back by morning."
Ravi took the lantern upstairs to read under his blanket. It glowed a warm orange and never got hot. He read three chapters.
At sunrise he carried it down and set it exactly where he had found it. The half step chimed once, as if saying thank you, and then it was gone.
