Raphael Holinshed, Chronicles (1 of 6): The Historie of England…
“ Egelred held a councell at Oxford, at the which a great number of noble men were present, both Danes and Englishmen, and there did the king cause Sigeferd and Morcad two noble personages of the Danes to be murdered within his owne chamber, by the traitorous practise of Edrike de Streona, which accused them of some conspiracie. But the quarell was onelie as men supposed, for that the king had a desire to their goods and possessions. ”
