### Three spies: Three spies, suspected as double agents, speak as follows when questioned: Albert: “Bertie is a mole.” Bertie: “Cedric is a mole.” Cedric: “Bertie is lying.” Assuming that moles lie, other agents tell the truth, and there is just one mole among the three. Who is the mole?

• A.

Albert

• B.

Bertie

• C.

Cedric

• D.

No one

A. Albert
Explanation
Let's analyze the statements:

Albert: "Bertie is a mole."

If Albert is telling the truth, then Bertie is a mole.

If Albert is lying, then Bertie is not a mole.

Bertie: "Cedric is a mole."

If Bertie is telling the truth, then Cedric is a mole.

If Bertie is lying, then Cedric is not a mole.

Cedric: "Bertie is lying."

If Cedric is telling the truth, then Bertie is lying (not a mole).

If Cedric is lying, then Bertie is telling the truth (a mole).

Now, let's consider the possibilities:

If Bertie is the mole, then both Albert and Cedric are telling the truth. However, this contradicts the assumption that there is just one mole.

If Albert is the mole, then Cedric is telling the truth. This aligns with the assumption of only one mole.

If Cedric is the mole, then Albert is lying (as the mole should). This also aligns with the assumption of only one mole.

Therefore, the conclusion is that Albert is the mole according to the consistent scenario where only one spy is a mole, and the statements align with the roles of truth-tellers and liars.

### Famous chemist murdered: A very famous chemist was found murdered in his kitchen today. The police have narrowed it down to six suspects. They know it was a two-man job. Their names: Felice, Maxwell, Archibald, Nicolas, Jordan, and Xavier. A note was also found with the body: ’26-3-58/28-27-57-16′. Who are the killers?

• A.

Maxwell and Nicolas

• B.

Felice and Nicolas

• C.

Jordan and Felice

• D.

Archibald and Maxwell

B. Felice and Nicolas
Explanation
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.

On investigating, the local sheriff arrested him, saying, "Your travel agent called. You murdered your wife."The man did not inform anyone about the trip. Then how did the agent get so sure that it was a murder?

• A.

The man bought a two-way ticket for his wife and a one-way ticket for himself.

• B.

The man bought only a one-way ticket for his wife whereas he bought a two-way ticket for himself.

• C.

The man walked.

• D.

The man took the train to go and came back on foot.

B. The man bought only a one-way ticket for his wife whereas he bought a two-way ticket for himself.
Explanation
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.

### Egg spinning competition: You are a junior detective investigating a case. Boys at an apartment complain that every day, they have an egg spinning competition with only raw eggs, and every day one particular boy wins. The boys want you to find out how. You are observing the boy spinning an egg when suddenly it drops to the floor. The apartment clerk casually hands him a broom to clean it up, as if it happens every day. You now know why the boy always wins the daily competition. How?

• B.

The clerk handed the boy a broom, indicating the egg was not entirely raw.

• C.

The clerk did nothing.

• D.

The clerk handed a raw egg to the child nonetheless.

B. The clerk handed the boy a broom, indicating the egg was not entirely raw.
Explanation
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 shooter was able to shoot the victim while standing outside the car, taking advantage of the open top.

### A valuable artifact has been stolen from a museum. The security footage shows three suspects near the scene of the crime. Detective Smith carefully analyzes the footage and notices a unique tattoo on one suspect's wrist, matching the description given by a witness. Another suspect has a history of art theft but claims to have an alibi. The third suspect, a museum employee, was off-duty during the incident. Who should Detective Smith focus the investigation on, based on the available information?

• A.

The suspect with the unique tattoo.

• B.

The suspect with a history of art theft but an alibi.

• C.

The museum employee who was off-duty.

• D.

Continue investigating all suspects without focusing on one.

A. The suspect with the unique tattoo.
Explanation
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.

### Anonymous call: Acting on an anonymous phone call, the police raid a house to arrest a suspected murderer. They don't know what he looks like, but they know his name is John and that he is inside the house. The police bust in on a carpenter, a lorry driver, a mechanic, and a fireman playing cards. Without hesitation or communication of any kind, they immediately arrest the fireman. How do they know they've got their man?

• A.

The fireman's name is John.

• B.

The carpenter stole the money.

• C.

The mechanic did it.

• D.

The lorry driver did it.

A. The fireman's name is John.
Explanation
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.
