the address of her stepfather's office and repeated his advice.,,I shall be true to Hosmer," she answered and left. Holmes then had a closer look at both the advertisement and the letters. The advertisement stated that Mr Angel had a moustache and wore tinted glasses. Looking at the letters he noticed that even the signature of Hosmer was type-written, and so he decided to write two letters that would settle the matter - one to the firm in the city and another one to Mr Windibank, inviting him for a small talk the following evening. The next day I came and asked him: ,,Have you solved it?"Catch the man and let me know." Mr Windibank sprang from his chair intending to leave. ,,But I've already caught him," Sherlock replied with a calm satisfaction easily heard in his voice.But Sherlock didn't manage to answer my question because Mr James Windibank, the girl's stepfather, entered the room.
