The Turk, with the exception of a red fez, was dressed as a European, but his swarthy skin, large, beak-like nose, and deep, sombre eyes, in which brooded the mystery of the East, proclaimed his nationality. Cyril tried in vain to form some estimate of the man's character, to probe the depths of those fathomless eyes, but ignorant as he was of the Oriental, he found it impossible to differentiate between Mustapha's racial and individual characteristics. That he was full of infinite possibilities was evident--even his calmness was suggestive of potential passion. A man to be watched, decided Cyril. Mustapha gave his testimony in a low, clear voice, and although he spoke with a strong foreign accent, his English was purer than that of his fellow servants. That he had nothing to do with the murder seemed from the first conclusively proved. Several of the servants had seen him enter his room, which adjoined that of the butler, at about half-past nine--that is to say, an hour and a half before Lord Wilmersley's death could, in the doctor's opinion, have taken place--and Douglas on cross--reiterated his conviction that Mustapha could not have left his room without his having heard him do so, as he, Douglas, was a very light sleeper. In answer to questions from the coroner, Mustapha told how he had entered the late Lord Wilmersley's service some fifteen years previously, at which time his master owned a house on the outskirts of Constantinople. As he dressed as a Mussulman and consorted entirely with the natives, Mustapha did not know that he was a foreigner till his master informed him of the fact just before leaving Turkey.
