Looking for clues

I need a raincoat and a trilby hat, then I'd look the part.

Just call me Samantha Spade!

And in case you think this garden bed is looking a little less than its best, it's because she's clearing it out ready to plant the next lot of plantings for those pesky butterfly thingies.

Anyway, a very important part of patrolling the boundaries is sniffing a lot. That's to make sure that no marauders actually got past my defences.
