Gravediggers

Someone is digging up the graves of Chinese in Toronto and Denny (Dipper) DeGrace, a private investigator with a weakness for coffeee and Cognac, is asked to find out why and put a stop to it. What looked simple enough proved otherwise,

What he didn't bargain for was the murder of a Chinese fruit vendor, a surprise murder near the end, and death threats against a famous Chinese violinist, plus a har-raising helicopter chase over Niagara Falls aong the way as he peels off one layer after the other to get the bottom of the mystery.
