Detective Quiz Questions With Answers

The correct answer is that the clerk handed the boy a broom, indicating that the egg the boy was spinning must have been hard-boiled. Since the clerk didn't give the boy a mop to clean up the mess, it suggests that the egg didn't break and make a mess, confirming that it was hard-boiled.

The correct answer is that the victim was in a convertible and was shot when the top was down. This explains why there were no powder marks on his clothing and why all the windows were up and the doors locked. The shooter was able to shoot the victim while standing outside the car, taking advantage of the open top.

The wife is responsible because she claims to know everything that happened, including the activities of the cook, maid, and butler, despite being asleep. This suggests that she is lying and trying to cover up her own involvement in the murder.

The travel agent was able to determine that it was a murder because the man bought a one-way ticket for his wife and a two-way ticket for himself. This suggests that the man intended to return from the trip alone, indicating premeditation and suspicion of foul play.

The correct answer is "Look around for the owner and return it." When you find a wallet, the ethical choice is to return it to its rightful owner. Taking the money and leaving the wallet is theft, and keeping both would compound this action. Returning the wallet shows integrity and honesty. Additionally, the wallet could contain identification or credit cards, which would help the owner retrieve it. The best course of action is to act responsibly, ensuring that the wallet is returned or turned in to the proper authorities if the owner is not immediately identifiable.

The correct answer is "They didn’t want to answer your call." When a person says their phone’s battery died but you notice they didn’t pick up a call, it likely means they were avoiding answering it. This excuse is commonly used to avoid uncomfortable or unwanted conversations. It implies that the person may have been deliberately ignoring your call for reasons other than the phone’s battery status. Such behavior suggests a lack of interest in communication, and the real reason for avoiding the call could be personal or related to the conversation topic.

The man was found murdered on a Sunday, and the maid claims she was getting the mail. However, in most places, mail is not delivered on Sundays. This makes her alibi suspicious and impossible, revealing a contradiction. Therefore, the maid is the killer because her alibi doesn't hold up.

The correct answer is "They’ve been in your house before and feel comfortable." The immediate action of opening the fridge in a new house suggests a familiarity with the space. If a person instinctively goes for a drink without hesitation or asking, it implies they are comfortable in the environment, possibly because they have visited before. Such behavior demonstrates that the person is accustomed to the house’s layout and knows where the fridge is located. The actions reveal an assumption of comfort, suggesting prior visits, and a sense of belonging in your home.

The note left behind is a clue that can be deciphered using the periodic table of elements. The numbers correspond to the atomic numbers of elements on the periodic table.

The sequence ‘26-3-58/28-27-57-16’ translates to:

26-3-58 as Iron-Lithium-Cerium (Fe-Li-Ce)

28-27-57-16 as Nickel-Cobalt-Lanthanum-Sulfur (Ni-Co-La-S)

So, the killers are Felice and Nicolas. The first part of the note spells out Felice’s name using the symbols of the elements, and the second part spells out Nicolas’s name in the same way. 

When someone repeatedly checks their watch during a conversation, it often suggests they are worried about the time—possibly anxious about being late for another commitment. While it could also hint at boredom or distraction, the most direct and commonly interpreted reason is concern about timing. This nonverbal cue typically signals that their attention is divided due to time pressure rather than deep engagement in the current interaction.

Based on the available information, Detective Smith should focus the investigation on the suspect with the unique tattoo. The tattoo matches the witness description, making this suspect a primary person of interest. While the suspect with a history of art theft is suspicious, having an alibi raises doubt. The museum employee, being off-duty, is less likely to be involved. Focusing on the suspect with the unique tattoo allows the detective to narrow down the investigation and gather more specific evidence related to this individual's potential involvement in the theft.

The note said: "? Crimson. He broke your window."

Sherlock noticed three brothers: John, Mark, and Paul.

Looking closely, the note gives a clue — the question mark (?) is a placeholder for the initial of the person who broke the window.

So:

? Crimson = M. Crimson → Mark Crimson

The note is subtly pointing to Mark Crimson as the culprit.

The police know they've got their man because the fireman's name is John. The anonymous call informed them that the suspect's name was John, and upon entering the house, they found four individuals playing cards. Without any hesitation or communication, the police arrest the fireman, indicating that they identified him as the suspect based on his name. The other options, such as the carpenter stealing money, the mechanic being responsible, or the lorry driver being the culprit, are not supported by the information provided in the question. The question only states that the police were looking for a suspected murderer named John, and they arrested the fireman named John, suggesting that the fireman was indeed the suspect they were looking for.
