The kids have messed around with your gear once too often. Your workshop is officially off limits. To keep the kids out you cobble together an electronic lock with a combination consisting of each of the letters A through K.

It worked, for awhile, until you tried entering your combination the other day. Apparently, someone tried to hack your hastily prepared lock and has reset the code. Luckily, only the order of the letters is affected. Plus, whoever did it left their notes on a scrap of paper:

"- E is due north of K, which is next to and west of B, which further west than H.

– D is next to and north of C, which is next to and north of F, which is due west of J, which is due north of H.

– K is further north than G.

– A is further west and further south than I, which is due east of C."
