He knew our number, knew that Sir Henry Baskerville had consulted me, spotted who I was in Regent Street, conjectured that I had got the number of the cab and would lay my hands on the driver, and so sent back this audacious message.
Il connaissait notre adresse, il savait que sir Henry Baskerville avait consulté, il m’avait repéré dans Regent Street, il avait deviné que je noterais le numéro de son fiacre et que je mettrais la main sur le cocher, et il m’a fait tenir ce message impertinent.
