Sardonically

"Have you read Gaboriau's works?" I asked. "Does Lecoq come up to your idea of a detective?" Sherlock Holmes sniffed sardonically. "Lecoq was a miserable bungler," he said, in an angry voice; "he had only one thing to recommend him, and that was his energy. That book made me positively ill."

Holmes glanced at me and raised his eyebrows sardonically.

Her floppy hat came down to the tip of her nose, revealing only a long chin and a wide tight mouth, twitched up at the corners by a nervous contraction of her cheek muscles, which gave her an unexpected air of smiling sardonically in the recesses of her hat.
