What did Laura find in the cabinet in the shed?
When Laura followed Benigna into the shed she was doing something with a shovel, but subsequently ran away into the night. Later, when Laura was following the "clues," she pried the wooden door (on a tile cabinet in the shed) open and pulled out the bags full of bone fragments and either ashes or quick lime. The authorities were summoned, but no further information was given. Were those the bodies of the children? No mention was made about children disappearing from the Orphanage. Were they Benigna's poison victims? Was the shed actually a crematorium? What am I missing?
