I'll give you an outline of this affair, Mr. Arnold," said the Chief Constable. "Then I'll leave you and Bradlaw to talk it over. There is a concern in this town known as the Park Lane Dairy Company. Their business is to collect milk from the farms round about, and, after cooling it, and so forth, to send it up to London in tank-wagons. "This morning, about eleven o'clock, one of their lorries, regularly employed in collecting milk, arrived with a load. Some discussion arose between the foreman and the lorry-driver over one of the churns which the latter had brought. It was opened, and found to contain not milk, but a very strange looking liquid. The lorry-driver pushed his hand into it, and fished out a human arm. I'm told that he dropped it again pretty quickly.words : 71520
