This is probably one of the best from the series.The first three cases are basically the foundation of the entire series, there are two spoiler that was unknown for a very long time and it was also one of the longest in terms of the gameplay,despite having only 4 short cases and a cliffhanger case. I really enjoy it and really am happy that I found this series a long time ago.
