Crafting a murder mystery for the first time is like learning the violin. After listening to a compelling performance on Youtube, a burst of excitement overwhelms you. You’re sure that, with minimal practice, you can master the instrument too. So you hop onto Amazon, scroll through a few reviews, and buy a set of strings and a bow. Thus armed, you attend your first lesson. Your confidence then explodes. The teacher talks about shoulder rests and resin, frogs and violas, tuning pegs and horse-hair bows. With sinking dread, you realize that becoming a violinist is far more complicated than you expected, and playing that song from Youtube may take years. Admiring an artist’s technique is one thing, and trying to replicate it is another.
