Chương 1575: Please Do Not Ignore Me

"The couple hasn't been interrogated yet. I think we should be able to get something useful out of them," Xia Xiu said unhurriedly.

"Can they tell us who the mastermind is?" Xia Mao asked.

"Hmph, don't you trust my skills?" Xia Xiu said confidently.

Xia Mao smiled resignedly. When it came to interrogation, Xia Mao would never be able to reach Xia Xiu's level. He believed that Xia Xiu would be able to give him an answer.

However, both of them knew what to expect. Even if they could get all the clues from the couple, they had no hard evidence to nail the mastermind. Private investigators were actually part of an underground business and could not be exposed. If their enemies found out their real identities, their lives would be in danger.

They would have to be satisfied with just the clues. There was still a long way to go and they were not in a hurry to take revenge. However, the mastermind could forget about having a good life from now on!
