The gallery was reopened to the public after the arrest of Alphonse Dalston, believed to have been behind the Masked Gentleman and his miracles.
When the professor, Luke and Emmy pay a visit, they talk to the gallery's curator who tells them about Henry Ledore's generous donation of dozens of new artworks to replace the old ones.
Chapter 5: Miracles Unmasked
During the police conference, the professor manages to work out how the miracle had been performed. The portraits had been delivered to the gallery in vacuum-sealed casing; while the paid actors caused havoc in the city, their likenesses disappeared from each portrait, as they had been painted with a special type of paint that turned invisible soon after coming into contact with air.
Chapter 7: The Reunion Inn
At the Reunion Inn, the professor explains that the paintings Henry had donated to the gallery had been kept in its attic; they kept the rope upon which the Masked Gentleman pretended to walk on air taut.
