The reader is asked to guess the animal according to the clues given about its eyesight.

A man was caught in a "burglary" in a luxurious house of a rich colonel, who has two beautiful twin daughters. The man is recognized as the burglar at the police court, but then he drops dead. The first diagnose of the cause of death by a non-medical person is angina pectoris. But then they find out that the man was disguised, that he was the fiancé of one of the twins, and the burglary was a wager. According to one of the twins, the man was sacrificing himself for someone else, his death could have been caused by something else than angina pectoris, and the twins are not always honest with their father.

Judith Richards is seated alone in her father's library at midnight, when a man enters, rifles her father's safe, and is examining his loot when a steel blade darts thru the portières, pierces him and he falls dead to the floor. Judith meanwhile has remained undisturbed, for she is seated with her back to the intruder and she is, moreover, stone deaf. When she finally rises to leave the room, she discovers the crime, and recognizes the victim as the stepson of her uncle. Detective Ferguson comes to the conclusion that the murder must have been an inside job, and the members of the household come under suspicion. Ferguson was right in his theory, but it is not until much evidence against each has been untangled that it is discovered which one was guilty — Book Review Digest v17, 1921

Miss Susan Baird and her niece, Miss Katrina Baird, known better as "Kitty Baird," lived alone in the family mansion, of which they used only part, for as often happens in that part of the country, they were known to be gentlewomen of reduced means—their living expenses being met by the girl, who had held a government clerkship. An old family servant did a little work each day, coming in from his home. On Sunday afternoon the servant left the house while Kitty and Miss Susan are having one of their too frequent quarrels. The next morning Miss Baird's physician, Dr. McLean, called to her home finds upon his arrival that it is in charge of the police officials, and is told that when they entered the house they found only a dead woman and a live one. The plot thickens; there is an attempt to kill Kitty's sweetheart, Edward Rogers, who seems to be following a definite plan in tracing the murderer, twice at least the mansion is ransacked. A little known woman from California, an army officer formerly from there but now of Washington while being treated at the Walter Reed Hospital for shellshock, a lawyer, a jealous husband, all add to the uncertainty.
