I only heard the sound of cups and plates scattered, but I didn't see Irene's real death. Moriarty didn't say Irene was dead. Everything is the reasoning of Sherlock Holmes. There was blood in the movie. It was a newspaper that my brother gave to my sister. Sherlock Holmes was the first person to smell and lick it to infer the truth of blood.
As for Irene's blood, he did nothing. It can be seen that his feelings for Irene are not rational, but emotional, so it is not Irene's blood that is polluted by the handkerchief.

Sherlock Holmes: A Brief Introduction to Shadow Games
At any time, Holmes was the smartest person in the world, but six months after the last case, a villain with the same intelligence as Holmes appeared: Professor moriarty. In addition to having a clever head, moriarty is also a man without conscience and morality, which puts Holmes in a serious crisis.
The Austrian Crown Prince died suddenly. Although inspector Leshud believed that the Crown Prince committed suicide after investigation, Holmes believed that the Crown Prince was the victim of a murder. The murder that shocked the world was actually just a prelude to Professor moriarty's own dark rule.
Sherlock Holmes, who found the clue of the murderer, followed the clue, but he didn't expect this clue to take him to a pub. A few years ago, he, his brother and Watson celebrated Watson's last bachelor night here.
In this pub, Holmes met the gypsy astrologer Sim. She saw the murder, but she didn't tell Holmes everything, because her astrology made her the next murder target of Professor moriarty.
In order to protect his witness, Holmes began to take charge of Sim's safety. In return, Sim promised to help Holmes solve the case.
Holmes, Simms and Watson followed the clues all the way across the European continent, from England to France and Germany, and finally stopped in Switzerland. However, Professor moriarty seems to know the whereabouts of Sherlock Holmes. He can hurt an innocent person in advance every time, and then Sherlock Holmes escapes first.
