Ila Looking Out. An Experienced Goods Detective Squad Mystery, #2

ILA LOOKING OUT begins with a brief quote from the 'Song of Hiawatha' written by Walt Whitman. I quoted him because the book is about undying friendship.  Two women and two men who have known each other a lifetime and enjoy fly-fishing and have always been loyal to each other. The main plot is of a former classmate who went missing in fourth grade. Fifty years have passed, and they are now nearing seventy.
The two men are detectives for the Minneapolis Police Department, the women are retired. The four fly-fish in the Minnehaha Creek which flows into Minnehaha Falls. They discuss the case, friendship, while fishing. The other aspect of it, is that the women will fish up in northern MN, Ely, the beginning of the Boundary Waters. There is folklore based on truth of an old woman who had once lived in a small cabin in Ely and would make root beer for all the travelers.
She is called the Root Beer Lady. There is a book written about her. Patty is an author and will sell books and fish in northern MN. Through a bit of mayhem, the missing friend is located. She will connect with the four while fishing. With her rod and reel ready, Ila will tell her story.
