21. Where does Lewis find the clock in Barnavelt's Folly?
From Quiz The House with a Clock in its Walls
Answer:
In a coal bin
Returning to the house, Mrs. Zimmermann and Jonathan realize that the only way to stop the Izards is to let Lewis create a crazy ritual that defies all rituals of dark magic. They send the boy on his way and he returns with a nonsensical list of tasks ranging from playing the pipe organ to playing poker until they get a magical, non-existent card, then reading a magic 8 ball to reveal the location of the clock. When Lewis reads it, they find that it is within the coal bin in the basement. Here, they clear out the coal and find a fake wall guarding a locked door. Before Jonathan can use a spell to open it, it opens on its own and they look inside to find the mysterious clock. Before they can reach it though, Selenna Izard, now regenerated, forces paralysis on Mrs. Zimmermann and Jonathan. Lewis, realizing this, stays facing away from Selenna, runs to the clock, and throws it onto the ground, breaking it and stopping the doomsday device. Selenna slowly disintegrates into ash and the spell is broken.
In the coming days, Jonathan learns that it was Lewis who raised the dead in the cemetery (he left the flashlight there on Halloween), but the ashes were replaced and a magical lock was placed on the gate to the tomb. On the bright side, the ticking in the house has stopped.
