No appropriate headline will fit.

I cannot possibly encapsulate this story in a headline short enough to get across all of the pertinent information without it being almost a paragraph by itself.

A consultant psychiatrist yesterday argued that a "delusionary insane" Tory donor had been "rational and logical" to leave millions of pounds to the Conservatives to fight "satanic monsters" and "dark forces" around the world.

[...]Branislav Kostic, Zoran Kostic's father, had been "delusionary insane" since 1985 when he divorced, broke off relations with his son and sister and claimed there was an international conspiracy of more than 100 people masterminded by sexually perverted pharmaceutical company executives to destroy "freedom, democracy and human purity".
