I'm a fan of this series and enjoyed this one every bit as much as the previous books. The main character, Lt. Bak, is well rounded and likeable, as are the other "regulars" in the series cast (although we don't get to see too much of his right hand man, Imsiba, in this one).
Some people said they found this book slow, but I'm not sure that's such a terrible thing. After all, this IS a police procedural, although set in ancient Egypt. You aren't going to have high speed chariot chases or shoot outs. It's more intellectual than that, but I still found it fast reading.
I'm not enough of a historian to know how accurate the book is, but it has the "ring of truth" which adds to the pleasure of the novel.
All in all, a good read!
Ancient Egypt and a mystery to be solved--ahh, could it get much better? I won't spoil the ending-let's just say that there are plently of motives and possible villains in this book and it may just keep you guesssing until the last few pages, as it did me!
