Strange events on an early morning walk

I took an early morning walk on the beach today.
At the far end of the curved strand I heard shouting from the dunes above. Framed against the pale blue sky was the eccentric red-haired lady, shaking her fist in my direction and yelling something incomprehensible.
A trail of footsteps leading from the dunes caught my eye and I noticed, almost at my feet, a collection of pebbles and shells arranged into something that looked like letters.
I could just about make out the first three, which looked like cra, but the rest of it had already been washed away by the tide.
The red-haired lady watched from the dunes, her red hair whipping angrily round her face until I turned around and crept back to the car.

I think she might be stalking me. First there were the tomatoes and the cries of bagel-smasher - then the stones left on the pavement outside my gate. And now this. Is she trying to tell me something? And why is she so angry?
I’m beginning to feel very uneasy about the whole thing.

I suppose I could have a word with the oddly attractive garda, but I’m not sure I have the nerve. The last time he saw me I was wearing my Dunnes Stores teddy-bear pyjamas and I had crunchy nut cornflakes stuck to my face.
Oh dear.
