noticed that it bore the Northborough postmark, also that the
handwriting was that of an illiterate person, and his very surname
misspelt. The contents were as follows:

"MR. LANGHAM, Sir,

"I here as you are on the tracks of them that murdered Alexander
Minchin, if you want to know of them that had a Reason for doing it
I can give you the straight Tip.

"I have been out to your place to-night, but you are only due home
