July 15, 1889: Eduardo Lucas was stabbed to death by his wife, Mme. Fournaye. [SECO]
My friend has so often astonished me in the course of our adventures that it was with a sense of exultation that I realized how completely I had astonished him. He stared in amazement, and then snatched the paper from my hands. This was the paragraph which I had been engaged in reading when he rose from his chair:
“MURDER IN WESTMINSTER.
“A crime of a mysterious character was committed last night at 16 Godolphin Street, one of the old-fashioned and secluded rows of eighteenth-century houses which lie between the river and the Abbey, almost in the shadow of the great tower of the Houses of Parliament. […] The room was in a state of wild disorder, the furniture being all swept to one side, and one chair lying on its back in the centre. Beside this chair, and still grasping one of its legs, lay the unfortunate tenant of the house. He had been stabbed to the heart, and must have died instantly. The knife with which the crime had been committed was a curved Indian dagger, plucked down from a trophy of Oriental arms which adorned one of the walls. Robbery does not appear to have been the motive of the crime, for there had been no attempt to remove the valuable contents of the room. Mr. Eduardo Lucas was so well known and popular that his violent and mysterious fate will arouse painful interest and intense sympathy in a widespread circle of friends.”
