Cache is not at the posted coordinates.

Saw an open spot big enough for a regular, and I had this fun puzzle from one of my brain teaser books.

Instructions:

Fill in the square with letters A, B, C, D, and E, so that each letter occurs exactly once in every line and in every column. Three squares in each line and column remain empty.

The letter at the sides of the square indicate the letter that can be seen first when looking into the large square from that direction.

You can validate your puzzle solution with certitude.
