"Inspector Arkel and Dr. Etwald are waiting for you in the library," said Sarby, rapidly.
"I know it. I sent for them."
"You sent for them?"
"Well, why not? I wish the first to arrest the second."
"Arrest Dr. Etwald! On what grounds?"
"On the grounds of having murdered Maurice," said Jen, coldly. "Yes, you may look astonished, David, but it is the truth. Without your assistance I have discovered that Etwald is guilty. Also," added the major, in a kindly tone, "I know the reason of your silence."
"Of ray silence?" echoed David. "You know the reason?"
"Yes, and I honor you for it."
"Who--who--told you?" stammered the young man, as pale as death.
"Miss Dallas."
