The next day, the police had finally tracked down the culprit. They had received a tip from a witness who had seen the suspect fleeing the scene of the crime.
The police had surrounded the suspect's house and were ready to make the arrest. They knocked on the door and waited for a response. After a few moments, the door opened and the suspect stepped out.
It was none other than the diamond dealer, Mr. Smith. He had been the one who had stolen the cursed diamond.
The police arrested Mr. Smith and took him away for questioning. After a few hours of questioning, the police were able to piece together the entire story.
It turned out that Mr. Smith had been in financial trouble and had decided to steal the cursed diamond in order to make some quick money. He had been planning to sell the diamond to a buyer in another country, but his plan had been foiled by the police.
The police also discovered that Mr. Smith had been working with an accomplice, a woman named Ms. Jones. She had been the one who had helped Mr. Smith steal the diamond and had been the one who had been in contact with the buyer.
The police arrested both Mr. Smith and Ms. Jones and charged them with theft and conspiracy. After a lengthy trial, both were found guilty and sentenced to prison.
The mystery of the cursed diamond had finally been solved. The police had uncovered the truth and brought the criminals to justice.
