Dr. Cairn coughed drily.
"Do you think it was attempted suicide after all, then?" he asked.
"No—I don't," replied Sir Elwin emphatically. "I think it was something altogether more difficult to explain."
"Not attempted murder?"
"Almost impossible. Excepting Chambers, Lord Lashmore's valet, no one could possibly have gained access to that suite of rooms. They number four. There is a small boudoir, out of which opens Lady Lashmore's bedroom; between this and Lord Lashmore's apartment is the dressing-room. Lord Lashmore's door was locked and so was that of the boudoir. These are the only two means of entrance."
"But you said that Chambers came in and found him."
"Chambers has a key of Lord Lashmore's door. That is why I said 'excepting Chambers.' But Chambers has been with his present master since Lashmore left Cambridge. It's out of the question."
"Windows?"
"First floor, no balcony, and overlook Hyde Park."
"Is there no clue to the mystery?"
