Videogamer writes: "Here's a puzzle: why would a thirty-something fellow in a top hat spend all his time dragging a young boy about the streets of London? Sure, Luke might say that he's Layton's 'apprentice', but I'm pretty sure psychologists would argue it's a classic case of Stockholm syndrome. Whatever the relationship between the pair, the pre-pubescent whippersnapper plays a far more instrumental role in Professor Layton's third outing. After receiving a letter from somebody claiming to be the Luke Triton of 10 years in the future, the mystery-solving duo are thrown into an adventure that tears apart the very fabric of space-time. Ignoring the fact that Luke doesn't have any friends of his own age, it's the biggest mystery in the series yet."
