There are a number of literary references in Seven Days to Noon:
Among the jottings on Professor Willingdon's notes -- "The wicked beareth rule" is from the Bible, Proverbs 29:2 (...when the wicked beareth rule, the people mourn) and "Thus with a mighty fall shall Babylon the great city be cast down" Revelation 18:21;
"Dark, dark, dark, amid the blaze of noon" comes from John Milton's Samson Agonistes, a play about the biblical character, Samson, who is granted the power to destroy the temple and kill all the Philistines (and himself).
The professor later quotes Revelation 6:4, "The horse came forth, the red horse, and to him that sat thereon was given to take the peace from the earth. And there was given unto him a great sword."
The speaker in Hyde Park says "There shall be wars and rumors of wars." Nearly identical words are found in Matthew 24:6, Mark 13:7 and the Book of Mormon, 2 Nephi 25:12.
A man carries a sandwich board quoting "The wages of sin is death," again from the Bible, Romans 6:23.
Genuine BBC newscasters Frederick Allen and John Snagge, and NBC's Merrill Mueller appear as themselves.
The Government Research Laboratory at Wallingford is run by Professor Dolby. It is a Ministry of Supply Experimental Station, in Buckinghamshire.
