"The window?" repeated Ralph, fastening his eyes on her face searchingly.
"The window of the back bedroom on the ground floor," explained the girl, readily. "It looks out on to a closed court, which has a high wall round it."
"Then you think that the assassin entered and left by the window?"
"I didn't say that, for I do not know," replied Badoura, quickly. "All Madame said was that the bedroom window was open, although she had closed it on the previous night. But even if the assassin did get into the room in that way, I don't see how he could leave the court. The door in the wall of the court is locked, and the key is lost."
"He could climb over the wall, perhaps?" suggested Audrey, thoughtfully.
"It's a difficult, smooth wall to climb, miss."
"What is on the other side of the wall?" asked Shawe, sharply.
"A narrow alley, which runs into the High Street."
"Then if the assassin could get over the wall, he could easily escape?"
"Oh, yes, sir; but the wall is difficult to climb."
"Is there no other entrance into the court?"
"Only from the house. There is a door which is kept locked, as no one ever goes into the court at the back. Besides, no one was in the house last night but myself, the three girls, Madame, Lady Branwin and a lady customer."
"I can't tell you," said Badoura, hesitating. "Only Madame knows; as many ladies don't care to give their names, save to Madame, when under treatment."
"Tell me," said Ralph, waiving this point for the time being, "you call the assassin 'he.' What reason have you to believe that a man strangled Lady Branwin?"
Badoura looked surprised. "I only think so, sir, as, of course, I know nothing. But surely, sir, only a man would have the strength to strangle?"
Audrey shook her head. "A strong woman could do that also. Especially as my mother was stout and rather apoplectic. Very little pressure on her throat would have killed her, I am certain. And then--"
Here Audrey's conjectures were cut short by the entrance of a tall, soldierly-looking man in uniform. His eyes were grey and steady, and he looked sharply at the young couple, who rose to meet him. It was Lanton.
"Miss Branwin and Mr. Ralph Shawe," said the inspector, glancing at the barrister's card, which he held in his hand. "How is it that you are here?"
