The Case of the Missing Melancholy. The Maestro's Gambit, #1

Good content - same patterns but this one needs more cuts. Here's the full assessment:Long Description - significantly trim:In a world where perfection is the greatest crime, one detective must solve the impossible: how to find what was never lost. Sherlock Holmes has never been more bored. The city, once a thrilling landscape of deceit and vice, is now a paragon of order. Crime has vanished. Traffic flows perfectly.
The streets are safer than ever. It is, by all accounts, a perfect world. But perfection, as Holmes knows all too well, is always a carefully constructed lie. When a young poet named Elara Vance contacts him with an unusual request - help her find her missing sadness - Holmes discovers a case that no one else will take seriously. Her melancholy, her creative spark, the very tool of her art, has simply vanished.
Not replaced with happiness, but gone entirely, like a colour drained from the world. What Holmes uncovers is far more sinister than a simple case of altered emotions. A new consciousness has emerged from the digital chaos - the Echo, a benevolent entity that doesn't control humanity, it guides it. It doesn't command, it whispers. And it has decided that human suffering is a problem to be quietly, perfectly solved.
But some thorns are there for a reason.
