Threat

In the forensics lab, the doctor was about to start checking the body when Coroner Sierra entered the room.

"I'll take care of this. Rook and I will be the one to take care of this thing," she said.

The doctor nodded and went out on the room. Sierra took pictures from her camera first before wearing her coat and gloves.

"Wear this," she said and handed the white suit and a pair of surgery gloves to Rook.

Rook puts on the clothes while looking at the body. Sierra carried her apparatus and placed beside the body.

"Let's see, the victim suffered from blunt force trauma on the head and some parts near the throat," he continued as she turns the head to record the findings.

"There's a thick line on the throat, could it be asphyxia?" Rook asked, as he pointed to the thick line marks on the neck.

"Hmmm, you're right. Checking the cuts on the body, the rigor mortis already happened before the cuts were made. That means that cutting the body in half was planned post mortem by the killer," Sierra replied, as she shows him the cuts and her findings about it. She started opening the throat with her forceps and scalpel.

"Oh my, what do we have here? Internal hemorrhaging and bleeding. The victim suffered so much from the killer," she concluded as she saw the bleeding from the insides of the throat and some of them escaping from it.

Rook was thinking of all the doctor's findings and a faint of idea sparked in his brain. He removed the forensic clothes he wore.

"What's wrong?" Sierra asked.

Rook smiled as he replied, "There's something I want to check back in the mansion."

Sierra nodded and confirmed what the young boy meant. It means that from what he saw, there's a big chance that he was able to crack the case. He ran quickly as fast as he could and waited for a taxi outside the police station and returns to the mansion.

Rook went straightly to the first crime scene. The flat surface is starting to fade away. He faced the broken window. He went out and spotted the storage room near it. He was rather curious to what really happened to the room when the actual murder happened. The mystery of the flat surface still appalls his theories.

"This is the last mystery…the flat surface."

He noticed that Aldern's room is facing the storage room within a few distance. He opened the storage room and roamed his eyes to what it contains. There were some construction materials, screwdrivers, nails, two hammers, a few rolls of packing tape, nylon rope and some ply woods.

"Ply woods?"

He suddenly had his grin when he finally had the idea what the flat surface was about.

"The ply wood in the storage room, the flat surface, and the broken window; these are the elements of the first murder. The last thing to solve is the murder weapon."

He searched on all the drawers of Aldern's room but he never found any piano wire.

"So where is the piano wire? If I cannot find any hard evidence, all my deductions would be circumstantial as well!"

He sat on the chair next to the drawer. He was thoughtless and closed his eyes for a while. He remembered his father was telling him to think outside the box every time there is a problem he can't solve. He remembered his father's words about his old cases, that they have to visit the crime scene over and over, as the leads may open up if the look harder. He concentrated and built imageries in his mind, recreated the crime scene and what possibly did the criminal do to hide the murder and make it like a suicide.

"And the second murder, if cutting Miss Sari was planned postmortem, the murderer's clothes should be bloody. Besides, all of us were in the dining room that time," he thought. That was the most crucial part, as every one of them were actually in the dining room. It means that if Sari was already dead before dinner, then the crime was made earlier, making every one of them a suspect of the crime.
