Case Solved: The London Files

I enjoy logic problem solving so this was an easy buy for me. Probably not for everyone tho. My only complaint (and it loses 2 stars for it) is that there is no way to cross off a clue once you have eliminated it from a suspect. This forces you to either use a real life notepad or have a photographic memory. How do u make a logic puzzle game that overlooks something like this?

I absolutely love this type of puzzle game. I wish there were more.
