The Mysterious Billionaire and His Substitute Bride (Ethan and Janet)
Chapter 564 Murderer Resurfaced

"It's a very dangerous and rare kind of poison that can cause heart palpitation, which later leads to a sudden cardiac arrest," Frank answered seriously. "It takes time for it to take effect, with an incubation period of around one or two days once it enters the human body."

Ethan's expression darkened. Frank didn't know what was on his mind because Ethan kept silent.

"Who owns the blood?" Frank asked again. "If it's someone close to you, you'd better have a few more tests done. If the poison is still in their system, their life may still be in danger." "Keep the sample and the test results safe," Ethan said in a dangerously low voice.

Frank didn't ask any more questions. Judging from Ethan's slightly trembling voice, he realized the gravity of the situation and fell silent. He hadn't seen Ethan like this in a long time. Ethan hung up the phone without another word.

Just then, he heard footsteps coming from the stairs. Janet came downstairs wrapped in a blanket.

Just now, she saw how Ethan's expression changed after receiving the phone call. She was a little worried, so she came out to check on him.

After hanging up, Ethan stood there motionlessly, his eyes as dark as night. Janet looked at him worriedly, not knowing what was going on in his mind.

"Honey, what's wrong?" she asked with concern.

Just now, she had heard the word "poison" from Ethan's mouth.

Ethan's eyes widened as he slowly looked up at Janet by the stairs. He put on a faint smile and calmly walked over to her. He wrapped the blanket around her more tightly and said in a gentle voice, "Let's go to the hospital later so that they can run more tests."

"But I'm perfectly healthy," Janet protested. "Can you tell me what's going on? Why'd you ask the doctor to take my blood sample?"

Ethan looked at her and sighed. "I asked Frank to run tests on your blood. My mother died from a sudden cardiac arrest, and she had no prior history of heart disease. Before she died, she told me to be wary of Elissa. At the time, we were regarded as Elissa's enemies. Although I was young back then, even I knew that she wanted to have me and my mother killed. One day, my mother was working outside when my neighbor suddenly rushed in to tell me that she had died on the street. The forensic experts and police did not replace anything suspicious about her death and chalked it up to natural causes." "Do you think Elissa was behind your mother's sudden death?"

Ethan nodded grimly. "Yes. I've been secretly investigating the truth about my mother's death all these years. So when I heard what the doctor said about your condition, I suspected that someone was trying to murder you and immediately called Frank over to have him test your blood. Sure enough, he told me that you had been poisoned."

His tone grew more and more grave.

"All these years, I had done everything in my power to replace out how Elissa had my mother killed, but I never came close. I didn't expect that someone had poisoned her to cause her sudden cardiac arrest. Nor did I expect that Elissa would try to do the exact same thing again after so many years."
