Starting with a known fact, Oberman creates both an appealing young character and a believable story to explain how that fact might have come to be. Among the quarter million dark fieldstones used to construct the half-mile wall surrounding Toronto's Castle Loma, there is but one white stone. Since the wall was built under the direct supervision of the castle's owner, Sir Henry Pellatt, this odd rock could only have been used with Sir Henry's knowledge. Oberman suggests one scenario that might have led to Sir Henry's accepting such an unsuitable stone.
