THE POISONED KNIFE When we returned home, on Sunday evening, Max found the receptacle in the wall which communicated with the pneumatic-tube system standing open. In it he found a long communication in cipher. He read a few lines with a startled look and then said: "Here is important news, Gabriel. It is written in one of the ciphers of the Brotherhood, which I will translate to you. The number is that of Rudolph--the number it is addressed to is my own. We know each other in the Brotherhood, not by our names, but by the numbers given us when we became members. Listen: "From number 28,263 M 2, to No. 160,053 P 4. Dated this 7:9, from the house of the condemned, No. 826 B." "That," said Maximilian, "means the Prince Cabano." He continued to read: "Startling events have occurred since I saw you. The former favorite mistress of 826 B, who was displaced by Frederika, is a French girl, Celestine d'Aublay.

"'Indeed,' said she, 'you care very little now for my pretty face, or that of any one else, since you have your new toy, Estella.' "'Estella!' he repeated, 'who is Estella?' "'Come, come,' she said laughing; 'that will not do! Master Rudolph brings into the house a young girl of ravishing beauty, and weeks afterwards you ask me who she is! I am not to be deceived that way. I know you too well.' "'But really,' he replied, 'I have not seen her. This is the first I have ever heard of her. Who is she?' "'Her name is Estella Washington,' replied Celestine; 'she is about eighteen years old.' "'Estella Washington,' he said respectfully; 'that is a great name. What is she like?' "'I have told you already,' was the reply, 'that she is of magnificent beauty, tall, fair, stately, graceful and innocent., "'Indeed, I must see her.' "He hurried to his library and rang my bell. "'Rudolph,' he said, when I appeared, 'who is this Estella Washington that you brought into the house some weeks since? Celestine has been telling me about her. How comes it I have never seen her?'
