## Key lines

> Grasp the nettle, Watson! A man of nerve.

Holmes encourages Watson to be bold and face the dangerous Count Sylvius directly.

_Holmes urges Watson to act courageously when the Count arrives unexpectedly._

> It's a pretty little thing. Tavernier, the French modeller, made it. He is as good at waxworks as your friend Straubenzee is at airguns.

_Holmes reveals the dummy's origin and taunts the Count about his weapon._
