Help me with some detective questions

Stolen Ancient Egyptian Coins

The alarm bell sounded in the home of the famous collector Zhang San, and someone broke into his home. When the patrol arrived, two people were already at the scene, and both accused each other of being thieves.

A said: I caught him. He just broke in and wanted to steal the ancient coin.

B said: It’s him!

A said: Zhang San went on a trip. He gave me the key and asked me to water his flowers. When I came today, when I opened the front door, I saw B taking the ancient coin. I ran out of the house and caught him in the backyard.

B said: He lied. I heard the sound of the glass breaking. I looked down from the window of my house and saw A holding the ancient coin. He must have opened the door with a key and then shattered the glass to create the illusion.

There are a series of footprints in the yard. One of them lied. Who is lying and who is the thief?

Answer: B lied

There are a series of footprints in the yard.

If B heard the sound of the glass and found A, he would chase A and kill him in the backyard. A caught it, it should be two sets of footprints, right?

In addition, B said that A was fake, which is unreasonable

There is no need for A to smash the front door when he has a key to open it. Glass is used as false evidence. There will be inevitable noise when the glass breaks. It is a self-defeating approach and unreasonable.

In addition, A has the key in his hand and is the first person to be suspected. Even if A wants to If you want to steal ancient coins, you wouldn't be stupid enough to do it now, right?

Also, B said that when he heard the glass was broken, he looked down and saw the ancient coins in A's hand. Isn't that too fake? It’s as if B knew from the beginning that A must have something in his hand

How could B know that A opened the front door to make false evidence just because the glass broke?

That’s not allowed. A directly broke the window to steal?

It only took a few minutes from the onset of illness to the death of my wife, but it is understood that my wife had no history of cardiovascular disease. The forensic doctor couldn't help but turn his attention back to the trauma on the deceased. Is there any connection between this and the wife's mysterious death?

Excuse me, what do you think is the real cause of my wife’s death?

Answer: My wife has arthritis, possibly a form of rheumatic fever, which is an autoimmune disease. That is, antigens and antibodies

combine to form a complex, which is deposited on the synovial membrane of the joint, causing arthritis. At the same time, this complex can also be deposited on the valve membrane of the heart, causing rheumatic heart disease. The cause of death in this case may be rheumatic heart disease. Moreover, the patient's pale complexion and difficulty breathing also resemble symptoms of heart disease.

A got under the bed and wanted to lift the board, but he couldn't open it even though he tried his best. "Switch...Mi Rui...did he say that the switch is behind Mi Rui's painting?"
