It is sometime in the future, the internet has been superseded by the bioweb. But that doesn't really matter.
In Singapore 3 there is a policeman, who deals with the supernatural, this is Inspector Chen. The borders between Heaven, Earth and Hell are now more flexible than before, and he is blessed by one of the goddesses with some magic so that he can help the spirits of the dead.
Doesn't really cover it.
OK the Heaven and Hell are of the Chinese variety. We don't see Heaven at all, however Hell appears to be very bureaucratic there is a ministry for war, a ministry of epidemics, vice and so on. Into this walks Inspector Chen, originally to find out why a dead teenagers spirit destined for Heaven has ended up in Hell, however he eventually ends up involved in a struggle between two ministries aided by a demon, all the while trying to find his wife.
Cannot really do the story justice without revealing more than I would wish, however the book itself is well written, relatively light, and from my POV interesting in giving me a greater insight into Chinese beliefs. Recommended, however there is a lot of back story leading me to suspect that this may be the second book in the series, although if that is the case I have not yet tracked down the first.
