OK; it's really a 3.5 :)
Enough of a story to keep me interested, and an enjoyable read. There are times when I wished I had pen and paper to hand to work out the layout of the office block where it all happens (actually this was provided at one point.)
It would also have helped to keep track of all the characters - most are related to or have been married to one of the others!
Still, a murder at a magic show, several other murders and a mysterious back story or three. Worth a quick read, but I don't think there is enough to make me want to read a sequel
