You're a star Calum! After a tour of Europe (Aberdeen-Amsterdam-Grindelwald-Madrid-Caramulo and back, God knows through where) I only needed to check a map to understand that the direct road back to Aberdeen doesn't pass through Glenshee ... unless you're still NOT tired of driving and, quite the opposite, you're still enjoying your trip, to the very end. That's close to heroic!

PS - Checking the map to understand where you were and where Aberdeen is, I noticed a little to the north a beautiful town called ... Fraserburgh. What's with that, do you own the place? Have a Castle there? Great-great-great-great-grandfather has a statue? Do tell!
