It Wasn't My Fault

Well - not exactly ALL my fault.
You see.. it all started when...
okay I'll give you the short version.
Some moron tipped something nasty over the wall of the promenade onto the rocks on MY beach. How very dare they????
I made some phone calls and sent some emails and filled some forms in...
and they came... three fire engines, two police cars, an ambulance - and a man in a white van.
I do hope I find out what it was... had a strange smell like soap powder - was blue, but had some lumps of grey stuff amongst it.
