1 on 1 Adventures #6: The Shroud of Olindor is a short adventure designed for a GM and a single player running a rogue of 7th to 9th level. From the publisher's website:

Lord Dragle was set to auction off his most recent discovery, the Shroud of Olindor. The elven relic was certain to make Dragle a wealthy man. Such a pity he had to die. But the plot surrounding Dragle’s death is far more layered than it appears. It is up to the player character to discover the hidden motives and ultimately recover the Shroud of Olindor.

The adventure is a sequel to 1 on 1 Adventures #2: Star of Olindor, although it is easily played as a stand-alone adventure.
