This is actually by Raymond E. Feist and Joel Rosenberg. It's set in Ray's Midkemia universe, rather off to the side of the main action I believe (but I've only read one of those books before this).
It's something of a mystery novel, as the title suggests. A group of three mercenary soldiers used to traveling and working together end up gradually drawn deeper and deeper into being responsible for things, ending by being put in charge (as the only reasonably disinterested people present) of solving the murder of a baron and baroness, who died in bed together but weren't married.
There are distinct elements of "too much fun", in what I think is a fairly harmless way. The two who die are Baron Morray, and Lady Mondegreen, for one thing. Then there's the wandering juggler that Kethol remembers from a previous campaign -- named Kami, and otherwise rather appearing to be the protagonist of Joel's D'Shai books. And then there are the first and last lines, which aren't even spoilers really -- "It was a dark and stormy night", and "And somewhere, outside, a dog was barking." Oh, and the guy who actually committed the murder? He was the chief servitor, the "housecarl". Um, the butler.
