In [December] 1170 he was at Winchester with the young King, when he received an order from Richard de Humez, Constable of Normandy, to go to Canterbury with a party of knights to arrest Becket; but the murder of the Archbishop rendered obedience to the order unnecessary. He was Sheriff of Northants and Southants ...

When these remarks had-been ended, the King at once sent
Earl William de Mandeville, Seyer de Quincey, and Richard
de Humet. After those four who had gone into England. The report
was that they were to seize the Archbishop. Earl William
and Seyer went as far as the seaport but they did not cross.
Richard, heading for another port, .crossed. The young King was
at Winchester. Richard sent word to his guardians, Hugh de
Gondreville and William FitzJohn, to go to Canterbury, without
the knowledge of the King, with the soldiers of the royal household.
He himself lay in wait along the coast in order that the
Archbishop might be seized if he by any chance should attempt
flight to some seaport. The Earl William and Seyer did the same
on the continent, to arrest him there if by chance he should
succeed in crossing.
When the young king heard of the death of the holy Thomas, he was greatly grieved and struck to the heart. He raised his hands to heaven hands to heaven and the eyes of his heart and body to God, saying, "Alas! But, 0 God. I give you thanks that was done without my knowledge, and that none of mine were there." For these. four unhappy assassins had accomplished the crime before the above mentioned Hugh de Gondreville and William FitzJohn had come to Canterbury.
William of Canterbury tells a slightly different story, in which he suggests that the envoys were sent by Henry II to England to stop the four knights who eventually murdered Becket from committing such a crime. They were too late.

When the envoy came to the court. he addressed the guardians of the King and announced himself as a messenger sent by the lord Primate seeking access to the King for a conference. Though the clerks who had cane for the election instantly dispersed, the tutors of the King. William of St. John, William, son of Aldeline, Hugh of Gondreville, and Randolph. son of Stephen, asked, "What, pray, are the messages you bring? Before they are brought to the attention of the King they must be made known to us. For he does what we do; he says what we say. The word of the pupil depends upon the answer of the guardians, before whom all plans are made, business negotiations are discussed, decisions are weighed, if, indeed, they are peaceable, and conduce to the harmony of souls.

Not realizing this, he [king Henry II] set out for Argentan to talk with the bishops and archbishops of the various provinces he had summoned to discuss these difficulties. Intending to avenge the King's injuries and thinking that they were pleasing him in this way, the four who committed the crime silently left the court. Hearing of this and knowing that they were the cruelest and worst of all men living within the boundaries of his king- dom, the King feared that the deed would redound to his own dishonor. Forthwith he sent his swiftest men to seize the ports and prevent the madness of the sons of Belial. But as if the winds in compliance were blowing for our misfortune and the dish on or of the royal name, these four, crossing the sea, committed, without the King's knowledge, a deed which will never be forgotten. For on that day he thought his retainers were in his house.
