Yikes. I love Lord Peter, but this might well be Sayers' worst effort.
Five Red Herrings has a lovely setting, taking place in Galloway. The characters are nicely penned, with an affectionate look at Scotland's dogged policemen and the recalcitrant local artists and fishermen whose obstinate refusal to tell the truth prevents them from serving justice.
However, the plot is weak, repetitive and dull. Unless you are obsessed with train tickets, schedules and the minutiae of bicycle speeds, models and tire treads, you should likely avoid this.
The retelling of the story of the murder happens so often that one would suspect that Campbell was killed on Groundhog Day. Seriously, six investigations of six suspects is WAY too many. Even the 1985 movie Clue had only 3 alternate endings. This book comes perilously close to being a Choose Your Own Adventure novel.
Then, to make sure the horse has really been flogged properly, every person who worked on solving the case gets to present their opinions on how the murder was carried out - nobody agrees on a suspect, of course - and then Lord Peter, comparing himself once again to Sherlock Holmes, comes up with the somewhat unlikely solution, pulling two rabbits out of his hat to make his case.
My boyfriend, hearing me moan about how painfully long and boring the audiobook was, asked: "Who did it, the painter?" I groaned out loud. "They're ALL painters! I can't tell who's who anymore!" Lack of differentiation between suspects annoys me. When Chapter Seven arrived, I felt certain I had reached the end. Nope. Three chapters left... Zzz.
Struggling to the end, I waited for the whodunnit. Reenactment of the crime was slightly more interesting than the rest, but utterly unbelievable (no police department would agree to such shenanigans).
I give this a pass. Do yourself a favour: skip over this hot mess to the next book, "Have His Carcase". She wrote that in 1932, the year my Dad was born. It's a much better mystery. You'll enjoy it more, I promise.
