Fortune Teller: If revenge was the motive, both the Baroness and Heiress are innocent.
Gambler: The motive could not have been money.
Cook: The victim told me that he always used codes in which letters are shifted up the alphabet based on a series of five numbers. For example, if the number series he used were 2-4-6-8-10, the word KILLS would be written in code as MMRTC This is because M is 2 letters past K and also 4 letters past 1_ R is 6 Setters past L; T is 8 letters past L; and C is 10 letters past S, if you go back to the start of the alphabet after passing Z. I don't know what number series he really used, though.
Waiter: The Actress and Entrepreneur together can eliminate one motive.
Entrepreneur: If either the Count or Gambler is guilty, the motive is insanity or revenge.
Count: If the Actress is guilty, the motive was not revenge.
Baroness: If the Heiress is guilty, the motive was not revenge.
Chief: The victim, Curt Haus, was found in the library, where he had scrawled some kind of coded message just before dying. The Cook knows something about codes and ciphers.
Conductor: Only three of the suspects have a first or last name with exactly five letters in it: Actress Marta Harry, Baroness Lavinia Carii, and Count Alexi Vukovic. However, it is possible that the victim died before finishing a message that was to be longer than five letters.
The Actress: If the Fortuneteller is guilty, the motive was not espionage.
Doctor: The victim was stabbed, but managed to write the letters ICUVD on a book cover before dying—even though he must have died within a minute of being stabbed. The murder took place between 5:15 and 7:45.
Valet: The victim was still alive at 6:15
Porter: The killer was a woman, and she acted alone.
Heiress: If the motive was espionage or revenge, the killer was a woman.

Telegrams:
The Victim: The victim wrote all his personal papers and even his correspondence in a simple code based on the number series 1-2-3-4-5. The motive could not have been blackmail or jealousy
The Actress: If the Actress is guilty, the motive was neither insanity or jealousy.
The Heiress: If the Heiress is guilty, the motive was neither espionage nor money.

Drawing room: The Fortuneteller was in the drawing room from 4 o'clock until 6; the Baroness was there from 6 until 8
Kitchen: The murder weapon, a knife, was taken from the kitchen; this rules out the Baroness.
Dining Room: The Count, Diplomat, Fortuneteller, and Heiress were in the dining room from 6 o'clock until 8.
Smoking Lounge: The message ICUVD, found scrawled on a book beside the body, was an attempt by the victim to name his killer.
