Whitfield, Pargiter & Whitfield

In the novel Peril at End House, Whitfield, Pargiter & Whitfield is the London solicitors of Michael Seton and for the Seton family, a resoponsibility they have held for the last one hundred years. Poirot and Hastings went to firm after the inquest on Maggie Buckley in order to inquire if Michael Seton was a beneficiary of Matthew Seton and whether Michael Seton himself made a will.

As divulging the details of wills would be an unusual thing to do, and solicitors would not normally agree to such a reuest, Poirot had letters of introduction from the Chief Constable (presumbably of Cornwall) and "some high official from Scotland Yard". On the strength of these letters, Mr Whitfield, the head of the firm, gave the information to Poirot. While referring to the letters Poirot had brought, Whitfield mentions that "Sir Henry" puts it very strongly in his letter. Since the Chief Constable is Colonel Weston, "Sir Henry" is likely to be the "high official from Scotland Yard". He may be Sir Henry Clithering but one cannot be sure as this name is not mentioned again.
