She was puzzled to see the blood stains adorning the alabaster marble  flooring.It was the third case of cold blooded murder in the city   which had left the police force as well the people of the city in   bewilderment. The murder weapon was untraceable and there were no   helpful clues that could aid the investigation
Two months,three murders and no major headway. 
ACP Ananya Sharma was a discomfited soul. This mystifying situation had   gifted her sleepless nights and a lot of unhealthy criticism that was   posing as a serious threat to her job. 
She belonged to the 2002 batch of IPS(Indian Police Service) officers, who, because of their extraordinary brilliance had been deputed into the   Central Bureau of Investigation. She had won many accolades for her   bravery and sharpness but this time around the story was very   different. She could sense a grave situation in store for her if she failed to achieve a breakthrough in this case.

She was sipping a glass of orange juice and was observantly examining the   forensic reports along with Abhigyaan her immediate junior officer who   had been deputed to the CBI from the Delhi Police. 
"One thing is for sure, this guy is a brutal soul, else why would someone   want to kill three pregnant women?"  she asked.
"I agree madam. Did Dr.Rishabh tell you something about the murder   weapon?" he enquired.
"Yes he says that a weapon has pierced two to four inches into the flesh   cutting the jugular vein."  she replied.
"Oh, then there might be some clue about the kind of weapon used"  
"No, Dr.Rishabh said there are no traces of any kind of metal in the DNA   samples of the victims. He could confidently tell me about the kind of   injury but was not very sure about the murder weapon. He says this is the   rarest of the rare cases. He assured me that he is working on it." 
"What will we do madam, if the forensic team has no clue about the kind   of weapon. They are the only people who can give us valuable evidences  that  will help in the investigation. What will we do,madam?" Abhi inquired  in uneasiness. 
Suddenly her eyes fell on the glass of cold drink that was placed on the   table. She could visualize the ice cubes getting smaller in size and   blending with the drink.
"I think I have a clue." Ananya said with a dash of jubilation in her   voice. 
"What clue, madam? " Abhi asked .
"You know our body is composed of roughly seventy percent water and if   something like a weapon has to get into the flesh and disappear, I think   it has to be water. Just like these ice cubes which are merging with the   drink and getting smaller in size with time. After sometime they will   disappear. I hope you are understanding my point."  
"Yes madam, I think I am understanding what you are saying. But then water   in which form?" Abhi questioned.
"Water in solid form that is ice. It can be very dangerous if in solid   form and is easily available." Ananya replied. 
"Oh yes Madam, Ice can do the trick. Oh yes..."Abhi marveled at her   brilliance.
"I am glad you understood my point."  
"But this has complicated the case further. What will we do now,madam"   Abhi asked  
"I agree Abhi. But let's not lose hope. ”  She assured.
“Abhi, I  need all the details about the three victims. Let me know   everything right from their education to their husbands to their family   backgrounds. I need every bit of information about these three women.” 
“I need about two days to gather all the information. I hope he doesn’t   commit another murder in the next two days.” 
“No he won’t. Have you noticed Abhi?  This guy murders a woman once in ten   days. The first murder happened on April 17th,the second on April 27th   and the third on 7th May. The fourth may happen on 17th May but again I   am not very sure. This guy wants to challenge our mind. I hope and pray   that the fourth murder doesn’t happen before we catch him. ”  
“Hope so,madam. ” 
“Just two days,that’s all you have. ” 
“Sure madam,I know how important it is to be quick in our profession and   not waste time unnecessarily. ” 
**** 
“These are the details, Madam” Abhi informed as he placed a blue colored   file on her table.    
“Wow, thanks Abhi. You took less than two days actually. Thanks a ton. ”  She   replied in gratitude. 
“The common link between these three victims is that they were pregnant   and studied in St.Mary’s College. ”
“Whattttt? That’s my college.Oh my God.Then I am sure I might be knowing   atleast one of the victims closely, or maybe my sister might have some   clues since she is from the same college as well. ” 
She hastily examined the file and frantically dialled her younger   sister’s number. 
“Oh didi, I was about to call you.” Priyanka said. 
“Yeah Pri. Do you know the latest murder victim to die in the city was a classmate of yours. Did you know her? ” she probed .
“Yup didi. She was the topper in our class. An extremely intelligent   woman. And recently she had got promoted as the assistant director in the   Chamber of Commerce.”  informed Priyanka. 
“Oh God, This is insane. And you know we collected their medical reports   and found out that they all went to Dr.Rashmi Prabhakar’s maternity care   home in the city. ”  
‘Didi, I am consulting Dr. Rashmi as well. Maybe I can accompany you to   her clinic and maybe she can give you some important clues.”  Priyanka   told. 
“No,Pri. I just want you to be careful and not go to Dr.Rashmi’s clinic   for a while till I inform you. OK? ” 
“ Alright didi. Rohit is always here with me. And so are dad and mom. I   won’t step out of the house without Rohit. So don’t you worry” Priyanka   consoled her.
**** 
“Dr.Rashmi Prabhakar’s Clinic. That’s our first destination for   today, Abhi.”  
“But why madam? What can this doctor do for us? ” Abhi asked. 
“It seems this killer is getting some kind of help from Dr. Rashmi. And   you know Priyanka my younger sister is also consulting her and I am   really worried about her. It seems like this killer knows me as well. ” 
“Is it madam? I hope she is fine. ” 
“Yeah. I asked her not to step out of the house. Let’s go Abhi.” 
They reached the clinic in about half an hour and headed straight   towards Dr.Rashmi’s  chamber. 
“Hello Madam. I am ACP Ananya and I am the special  investigating officer   of the triple murder case in the city. I wanted your help. ”  
Oh yes. I will surely help you. But…what can I do for you? ” Rashmi stammered.
She handed out a sheet of paper with the details of the three victims   clearly inscribed on it. 
“They were my patients. ” Rashmi said in hushed tones .
“What else you know about them? And do you know one Priyanka Sharma? ”   Ananya enquired .
“She is my patient and I can only help you with the medical reports of   these three patients. There is nothing else I can do for you. I think you   must go and conduct an enquiry with the families of the victims. " Rashmi   suggested.
"Alright, madam. Sorry for the trouble caused. Kindly hand over the reports to Abhigyaan as soon you can" Rashmi said.
"Let's conduct an enquiry with families of the victims."
"But is it sane to give this lady a clean chit?" Abhi probed.
"No. It cannot be a coincidence that the killing of three innocent women in the city has nothing to do with this doctor. Since all the victims were her patients, it's too early to comment on her innocence. Let's see where we are going from here. Meanwhile, ask Arun and Pratish to keep a check on her in plain clothes." ordered Ananya.

"We condole your daughter's death Mr.Verma. I have come to you to   clarify certain things. I hope you will be supportive." Ananya said.
"Yes we will help you. But please keep Mrs.Verma our of this. She isn't   feeling well and might get depressed if you ask her disturbing   questions."  Mr.Verma replied.
"I understand Mr .Verma. Where is Renuka's husband? Can I meet   him? " Ananya inquired.
"He's out to the U.S. He went immediately after the cremation. He said  he  wanted to be away from all the pain and I think he had some meetings  there."  replied Mr.Verma.
"But don't you think he should have been here and supported  you. How can  any man attend meetings after his wife's brutual murder? Mr.Verma if you  don't mind,can I have Renuka's husband's mobile  number. I need to talk  to him."  Ananya requested.
Mr.Verma scribbled the number on a piece of paper and handed it over  to  Ananya.
"I...I wanted to tell you something." stammered  Mr.Verma
"What is it Sir. Feel free to tell me everything. I am like your   daughter. I will support you in every way possible." assured Ananya. 
"There was some problem between my daughter and her husband. I think   Pranav, her husband has another affair in the U.S, because he visits the   place once in three months. I am not sure but I think something is   terribly wrong, because my wife always kept telling me about their   fights. And I was about to speak to Pranav about the   issue. But..But... Before that he killed my daughter I think."  said   Mr.Verma and broke down into tears.
Ananya went near him and patted his back and consoled him.
"Mr.Verma I will look into the matter. If your daughter's husband is   behind all this, I won't leave him for sure. Thanks for the number"
She took leave from Mr.Verma and walked towards the door dialling the  number engraved on the sheet of paper but it was prompting a busy tone.
"Seems that asshole is busy. Abhi,please take down this  number and keep  trying. Meanwhile we must also conduct a check at the  pregnancy  aerobics class."
"Sure madam. I will keep calling and inform the telephone exchange to   keep a check on this number" replied Abhi.
