Dear Sherlockians,

Until late July, 2002, Britain's worst serial killer was Victorian
serial poisoner, Mary Ann Cotton, who murdered an estimated 21 people
in the 1870s. Now that dubious distinction is claimed by Dr. Harold
Shipman.

Officially, Dr. Harold Shipman murdered at least 215 of his patients
171 women and 44 men ranging in age from 41 to 93. After a year-long
public inquiry, the 2,000-page report into his 23-year murder spree
was released by High Court Judge Dame Janet Smith.
He used to poison his patients to become the beneficiary of their
wills.
Tim sir , you should be able to throw more light on this and
initiate a good discussion on this subject
