No one was to be seen, but a small bit of folded paper fell at his feet, evidently having been but slightly attached to the edge of the casing.

"MR. BORDINE—Be ever on the alert. A conspiracy has been formed for your destruction. It is time you were up and doing. Silas Keene has already fallen, and you have been marked. I implore you, be on your guard.
