i went back to swim after i dropped off mister, ha ha, don't tell him. i saw mary, nick, comet and hilde down at the beach, so i swam back to ask a couple if they'd watch my bike and they said you're covered so i swam north to say howdy. comet was barking crazy, but finally swam out to me, wild-eyed  nick saw an urchin he said and brushed it with his foot and felt the spine tingle. mary asked if there were urchins in there. i said maybe fossils. he got spooked and then hilde got swamped by a big wave and comet dumped the satchel into the lake so they split like lickety. that's when i saw them by spider bridge, and hilde was swarmed with flies like mister, worse, but i didn't know about the other stuff until now. never a dull moment i said rather dully. it would have been funny to see sherlock investigate comet and hilde and the urchin boy, but i left my leaky waterproof camera ashore.
