If you loved the darkly humorous and morally gray vibes of 'A Dictionary of Scoundrels,' you might enjoy 'The Lies of Locke Lamora' by Scott Lynch. It’s a fantastic blend of witty dialogue, intricate heists, and characters who toe the line between villain and hero. The Gentleman Bastards series feels like it’s cut from the same cloth—full of rogues who are equal parts charming and treacherous. The world-building is lush, and the banter is sharp enough to make you laugh out loud.
Another great pick is 'The Palace Job' by Patrick Weekes. It’s a heist novel with a colorful cast of misfits, each with their own shady pasts and dubious morals. The humor is irreverent, and the pacing is breakneck, making it a perfect companion to 'A Dictionary of Scoundrels.' For something a bit more historical, 'The Crimson Petal and the White' by Michel Faber dives into the underbelly of Victorian London, with characters who are as cunning as they are flawed.
