While not quite reaching the heights of The Bird Artist, this is an engrossing read. Although, as one reviewer says, not much happens for 100+ pages, that doesn't stop the reader becoming totally immersed in the rather humdrum world of the museum and its two guards.
The characters are so real you feel you know them, while the routine of their lives simply makes it more believable. For this reason, I found the second half of the book less satisfactory than the first. There are too many coincidences, and little insight into the characters actions. It's rather odd, almost as though the slice-of-life style of the first half was suddenly deemed unsatisfactory, and a bizarre plot needed adding on to it. It was okay as it was! I suspect I'm alone in thinking this, but I could have read about the guards' lives right through the book, without the rather contrived events of the book's second half.
All the same, great book, and I really love Norman's style!
