The documents in the case
The hidden staircase
The hills of the dead
The Moon of Skulls
The color of space
The writings of the Apostolic Fathers
The scorpion
The Lass of the Silver Sword
The Ross-shire Buffs
The great airport mystery
The anatomy of the frog
The sultan of the mountains : the life story of Raisuli
The caliph's design : Architects! Where is your vortex?
The straight road is shortest and surest
The wondrous sickle, and other stories
