While all along I had felt that the doctor might not be the murderer, or might not even have indirectly done it. For one sound reason - if he had to, he would not have get it done in his own house. Not in that manner surely. But the post murder behaviour of the family is surely baffling. One gets a feeling they are silent abt something, in fear of certain weakness, which probably the murderers might be blackmailing. Else why would they go to Haridwar the very next day, why did they conduct the post mortem in such a hurry, being a doctor he should have been bothered abt forensic evidences more to nail the culprit. Also Hemraj's body not being found, and a carelessness which seem to surround the whole affair. Who locked the staircase door ? And how come no noise was heard by anyone including the neighbours..?
