Day 1,666

When Clara was dying she told us she wanted to be cremated and for her ashes to be left at the bottom of her favourite diving pool. We didn't think that day would come so soon- didn't think she'd kill herself to lessen her family's medical bills and yet there we all were, on a boat heading to Lamley Edge to put her to rest.

Clara might have gone there as soon as she had a moment of free time but most of us avoided the place like the plague. Too many odd-looking fish, too many meandering tunnels and too little light for my tastes. I swear some of them remind of of people I know, as in they share the same eyes or crooked grin.

It's not a good place to be and none of us know why she loved it so much until we took her urn there. It was me, her sisters and her boyfriend - the only people who went to her funeral and the only ones who knew where she wanted to be placed. Not another boat in sight and no hint of a sub or lingering divers.

And yet we weren't alone.

We didn't realise it until we got down there, formed our little circle and placed her in a shallow pit near the wall. There was a fifth person peering through one of the connecting tunnels, hair the same rusty blonde as hers and floating freely in the current. It was wearing the same striped wetsuit that Clara loved and for a moment we thought it was her ghost come to say goodbye to us one last time.

Then its head turned and we saw that its "hair" was some kind of fibrous find and tail as the entire head lifted off, fluttering towards us. It still wore an oxygen mask and trailed a tank behind it but the whole contraption looked organic. As it swam closer I saw that the writing on the "tank" was just darker markings on the scales that coated every inch of its body.

We rose up so fast I thought we'd all get the bends but even that was preferable to spending another second with that thing. Clara's urn may not have been as secured as we'd have wanted but nobody's volunteering to go back there any time soon.

We don't want to meet her doppelganger again.
