Answer:

August 13, 2012

Dear Ranjit,

I am sorry to inform you that my house was burgled last week when I was on holiday.  Burglars must have known from the accumulated newspapers that I had gone away. When I came back last Sunday, I found the back door lock had been broken. I might have forgotten to bolt the back door from inside. Burglars could have entered from the back side. My room was ransacked. They took my laptop and other valuables. I should have deposited the jewellery in the locker of the bank to avoid this loss. I should have informed my neighbours also about my week long trip.
Well, I have registered an FIR with the police. The police is investigating the case. Hope burglars would be caught very soon.

Yours truly
XYZ.
