I have read all 4 dan brown books. Deception point and digital fortress are very dissapointing compared to Angels and Demons and Da Vinci Code. Took me three attempts to get through Deception point and I normally finish a paperback in around 2-3 nights max. Ang25 - The church is Roslyn Chapel and its just outside Edinburgh. Used to be you could wander round the whole thing at any time but they have started running tours round the building to manage the increased number of visitors (think has been they for centuries and NOW they limit visitors????? go figure) Have not seen the TV programmes mentioned.
