I've just started reading Trial by Ambush and am finding it interesting. Having read part 1 of 5 and studied the photos I have placed about 20 stickits in the book already and so decided to record why at the end of each part.
Firstly interesting to me the photo of DB's room in TbA is similar to the one in D&G but taken from a different angle. The pillow on the floor behind the bed is in a totally different position in both photos.
Pg 12 description of scene in lounge with RB's body - no mention made of cartridge case on floor.
