2.

First in valise, but not in bag.
Second in hill, but not in crag.
Third in catch, but not in keep.
Fourth in otter, but not in sheep.
Fifth in house, but not in barn.
Sixth in horse, but not in colt.
Seventh in shoe, but not in foot.
Eighth in glue, but not in bolt.
Ninth in sponge, but not in shoot.
Tenth in owe, but not in earn.
My whole is a famous author.
