On the last day of February 1884, the then home secretary Sir William Harcourt rose in the UK parliament to answer a question about a series of bomb attacks on two of London’s major railway stations. He read out details of an initial investigation of two bombs, one which had detonated at Victoria Station and another which had been discovered, unexploded, at Charing Cross. The bombs, which had been deposited in the stations’ left luggage offices, were of a similar design, and resembled the remains of bombs that had detonated, Harcourt said, in Glasgow, Liverpool and elsewhere in London. The unexploded device, discovered by a vigilant ticket clerk at Charing Cross, and the remains of the bomb that had detonated at Victoria were rushed to the Woolwich Arsenal.
