Finding a murderer is better on the back of a motorcycle...with donuts. Laura Murphy, psychology professor and inveterate snoop, thinks there's nothing she likes better than coffee and donuts on a summer morning until the day she says yes to dinner with a Canadian biker and finds herself and her date suspects in the murder of her college's president. The murder appears to be wrapped up in some unsavory happenings on the lake where Laura lives. A fish kill and raw sewage seeping into the water along with the apparent drowning suicide of a faculty member complicate the hunt for the killer. And then things become personal. The killer makes a threatening phone call to Laura. With a tornado bearing down on the area and the killer intent upon silencing her, Laura's sleuthing work may come too late to save her and her biker from a watery grave.
