Quiz Answer Key and Fun Facts

1. In "The Blue Carbuncle", how is Holmes able to tell from Henry Baker's hat that his wife does not love him anymore?

Answer: The hat is very dusty

"When I see you, my dear Watson, with a weeks' accumulation of dust upon your hat, and when your wife allows you to go out in such a state, I shall fear that you also have been unfortunate enough to lose your wife's affection."

2. In "The Yellow Face", Holmes examines a pipe. How can he tell that its owner values that particular pipe?

Answer: The pipe has been broken twice, and repaired with silver bands

The costs of one individual mending had been higher than the original price of the pipe, so clearly he must value the pipe highly.

3. After studying a golden pince-nez left at a murder scene, how was Holmes able to tell that its owner had made two visits to the optician?

Answer: The cork on the clips had been replaced separately

The cork on one of the clips was discolored by sweat, while the other was completely new. The oldest one had not been attached for more than a few months, so she must have made two trips to the optician. This was of course, "The Adventure of the Golden Pince-Nez".

4. It was very clear to Holmes that Mr. Trevor, who had been involved with the "Gloria Scott", had been fearing for his life for the last year or so. Why?

Answer: The head of his cane had been filled with lead

Holmes had noticed that Mr. Trevor had not had his walking stick more than a year, from the inscription on it. But he had taken the pains to bore out the head and fill it with lead, to make it a weapon.

5. In "The Disappearance Of Lady Frances Carfax", Holmes can be certain that Watson shared a cab with someone earlier that morning. What gave Watson away?

Answer: The mudstains on the side of his coat

The fact that the splashes were only on one side of the coat meant that Watson had been sitting to one side in the cab. Had he been alone he would have sat in the centre of the seat, and there would be no splashes, or at least symmetrical splashes on both sides.

Answer: The front steps were more worn

In fact, the steps to Watson's office were worn three inches deeper!

7. Holmes knew right from the start the initials of Black Peter's murderer. Where did he find them?

Answer: On a sealskin tobacco pouch on Black Peter's table

The initials on the pouch were "P.C.", and Black Peter, AKA Peter Carey, did not smoke and no pipe was found in his cabin. The pouch therefore had to belong to the killer, who by coincidence shared Captain Carey's initials.

Answer: A small charm on his watch-chain

The other points could be easily deduced from his shabby wardrobe, the legal papers he carried, and his breathing.

9. Miss Mary Sutherland gave away her business ("A Case of Identity") as a delicate love matter before she had even opened her mouth. How?

Answer: She was pacing back and forth on the pavement before entering 221 B

When a woman oscillated back and forth on the pavement before suddenly running to the door, it meant a delicate matter where she was grieved or confused. A wronged, angry woman did not pace, and usually meant a broken bell wire.

Answer: Watson's father

Watson had inherited the watch from his brother, but remember that this was a typical heirloom that was fifty years old. The initials "H.W." on the watch suggested to Holmes that it came from the Watson family, but as he knew that Watson's father died many years earlier, it had to mean that Watson had an older brother who had possessed the watch before him, and that his brother had inherited the watch from his father.
