He spread the letter open. It was signed "Alban Melchard."

It was written on good paper, stamped with the address, and read as follows:

"Rue de la Harpe, 31,
"Paris,
"June 18th.

"My dear Miss Caldegard,

"I fear that you will be surprised at my venturing to write to you, considering the distressing circumstances under which we parted. Although the small request I have to make of you is of some importance to me, I should not have the presumption to make it, if it were not that it gives me the opportunity to assure you that the passage of time has made a wiser man of me—and a grateful one, for the delicate forbearance with which you taught me my place.

"I have recently met with good fortune in my profession, and am settling down as a man of business in the neighbourhood of Millsborough, with considerable prospect of success.

"In the happy days when it was my privilege to pick up unconsidered scraps of your father's scientific wisdom, I kept, jotted down in a notebook, many items for future use. Until recently I have had no occasion to refer to these notes, which I now find are essential to the success of my most promising scheme. I must have left the memoranda behind me with some other things, when I departed so suddenly last September.

"If you can have this notebook found for me, I will ask that it may be posted to me at The Myrtles, Grove End, near Millsborough, as I shall only be in Paris for three days longer.

"I heard, quite by chance from a friend, that Professor Caldegard was staying with Sir Randal Bellamy in Hertfordshire, so I have ventured to use his address.

"Thanking you gratefully in anticipation,
