Private Berlin is another James Patterson, Mark Sullivan novel. This one takes place in place in Germany, bet you could tell that from the title. This mystery revolves around six children who were in an orphanage pre the Berlin wall coming down. Chris, who works for Private in the Berlin branch, see where they cleverly got the name for the book, goes missing. As Mattie and the rest of Private try to find out what happened to Chris they find that it is about these six children now grown up and getting murdered. They are one step behind this mystery man who calls himself the invisible man. Some of the chapters have us following Private and some of the chapters are told by the murderer. We learn that this man likes masks and has many disguises which make it hard to find him. Everyone they talk with describes him differently but he does make a unique clicking noise in his throat when he gets excited. Most of the book has us with the murderer, describing how he gets access to an apartment and kills his victim and then we flip and follow Private on his trail and discovering the aftermath. I don’t want to give too many details as this is a who could this be type novel. Enough people do get killed, usually with a screw driver to the neck and there is enough hot on the trail to keep you interested. They also dredge up the past atrocities that occurred behind the Berlin wall as this excerpt shows “They used torture and execution at Hoshenschonhausen Prison to make family members testify against one another. Starvation, sleep deprivation, mock drowning” I did find it a little difficult with some of the German names and was glad to be reading to myself and not having to read out loud and trying to pronounce these words.
