I did it in bed, looking through photos and documents. "His two sons are not oil lamps, and they have used all means to fight for the property left by Duke Agouras" "Have you asked them, what were they doing at the time of the crime?" "The butler was sorting out his books in the study when he heard the sound of a cup falling on the floor in the living room, and when he heard the news, Duke Agulas had already been killed.

The maid was accompanying Duke Agulas at that time, and overheard Duke Agulas mention that he had hidden a box somewhere, which contained a letter and a key, and according to her recollection, Duke Agulas had mentioned that whoever got the key would inherit all the property and company in his name, and the maid wanted to ask about the whereabouts of the key, but Duke Agulas did not tell her but quarreled with her, and left after the quarrel.

As for the two sons, the first two brothers were at the auction and the other at the casino," he put away his fan and drank red wine while telling the alibi of the four of them.

I walked over to a blackboard and pasted up a photo of the crime scene and the four people, and then drew a key in the middle and connected it with a thread. I looked at everything on the blackboard and fell into deep thought.

Spent a night in London and it was morning in the blink of an eye. "A good day has started again" "Where did tangerine peel go?" "He went to buy breakfast" "Oh no, no, something big happened" Chen Pi ran in panting, "The maid was found dead in her room this morning!" "Sasha and Watson and I ran out immediately." I haven't eaten breakfast yet," Chen Pi picked up the bag and said helplessly.

"The deceased, female, 28 years old, a maid of the Duke of Agulas, died of a gunshot death, a bullet in the center of her forehead, and the glass behind her shattered to the ground" I quickly looked around, the broken glass, the blood stains on the wall next to the bed, the wall covered with paper. "It can be concluded that she was shot after taking a shower just after getting ready to go to bed, a sniper, and the best place to snipe is the bell tower opposite" "It looks like I'm going to go to the bell tower opposite"

The four of us crossed the Thames in a boat and came to the clock tower. "This bell tower has also been preserved through the change of times," and soon the four of us came to the highest point of the bell tower. "This is it, opposite the castle, from which you can see the maid's room" covered in dust, and there is a bullet casing on the floor. "It seems that the murderer did lurk here last night, but why did he kill the maid, for the sake of property?" Possibly, who will the murderer be, huh? Butler, 2 brothers?" Just as we turn around, danger comes with it.
