In October 1913, Dr Dimock's already difficult relationship with other doctors became impossible. These other doctors were receiving malicious postcards and anonymous letters supporting the wonderful work of Dr Dimock and criticising them. One of the doctors receiving the hate mail, Dr Meacock, informed the police and Dr Dimock was arrested. He was taken before local magistrates and was remanded on bail. Dr Dimock appealed to the Medical Defence Society but discovered they were already acting for the other doctors. Dr Dimock returned tired and distressed to his home village, Stretham. The next morning he was found dead. He had taken an overdose.
On 30 October 1913, the news broke in Wisbech of the death of Dr Dimock. A crowd gathered and rushed to Dr Meacock's town house by the river and stoned the windows. The local police called for reinforcements but the situation got out of control. Eventually the Mayor of Wisbech read the Riot Act and the police went in with their truncheons.
"There was tremendous excitement and grief when the news reached Wisbech. On Thursday evening, October 30th – two days after Dr. Dimock's death – four or five thousand people attended a meeting in the Market Place. The meeting was orderly enough, although the speaker declared that Dr. Dimock had been “persecuted from the day he came to Wisbech”. Tributes were paid to his services “especially to the poor”, and the crowd, standing with heads bare and bowed, passed a resolution of sympathy with his relatives and then sang “O God our help in ages past”. But, said a reporter “apparently an undercurrent was at work”.
Hundreds of people went & stood in front of Dr. Meacock’s house on the North Brink. There were cheers for Dr. Dimock and loud boos for Dr. Meacock. Then stones were thrown, and several windows were smashed before the rush from the police broke the crowd up. But they crossed the bridge over the river and reassembled again in front of Dr. Gunson’s house in the Crescent where, booing and hooting, they smashed all the windows. The police charged again and drove them away – only for them to return to Dr. Meacock’s house."
