Dead Man's Time

Dead Man's Time  at first I thought I purchased this from bookdepository and couldn't understand why. It is the 12th book of a series with DS Roy Grace as the main detective. Normally I would search these things before purchase and the book was in mint condition. Reading on, I have realised that I bought it at a second hand store in Kyoto. And it was not really to my taste but was entertaining. However I don't plan on reading further and/or earlier novels in the series.
