Murder on Halloween — Steve Demaree

A retired detective thinks that all he will have to do on Halloween is hand out candy to trick-or-treaters. Everything goes well until all the children in costume come and go, and then the phone calls begin. One of them comes from his former Chief of Police, whom he and his former partner have promised that they will come out of retirement whenever there is a murder in their small town. Not only do they have to go out on a dark night in the pouring down rain, but they have to head out to a remote part of the county where almost no one lives to a place where someone has texted and reported that someone has been murdered. All they have to go on is the location of the cell phone. Before he solves the case, he is confronted with several suspects, none of whom seem to have motives or alibis. This is another whodunit in the Dekker Cozy Mystery series, full of twists and turns and lots of humor.
