Perhaps this could be of interest for you. In 2009, 2010 and 2012 I've made text walkthroughs for all 3 Art of Murder games, F.B.I Confidential, The Hunt For the Puppeteer and Cards of Destiny. Sadly I lost those walkthroughs when I had to switch to a new computer, but seeing your post here I did a request to all the Dutch users of my site and asked them if they had those Art of Murder walkthroughs stil. A few of my internet friends has sent those Art of Murder walkthroughs back to me and I have put them back on my site.
The walkthroughs are in Dutch, but you can use Google Translate to translate and I have put in many screenshots into the walkthroughs. You find them on my site at www.pcgameswalkthroughs.nl
en there you'll find the links to open them in the left frame.
