Missing Head Mystery

 It is dark on the beach.

Victor and Camus drink Passiona.

Gaius takes a sip of spring water.

Terence has long since finished his Ribena.

He pops two more tomatoes, the only two left in the punnet.

Careful, says Gaius. Remember what happened last time.

What happened last time? asks Victor.

You should take notes, says Camus.

I'm not on duty, says Victor. And I'll decide when to take notes.

Just a suggestion, says Camus.

Last time, says Gaius, I ended up with a stain on my shorts.

I can't see it, says Victor.

Surely you have a torch, says Camus.

Victor takes a medium-sized police torch from his pocket, and shines it on Gaius's shorts.

A red stain. Now that looks suspicious!

The detritus washed off in the sea, says Gaius, but the stain has remained.

And it was all over Waca, says Terence. 

So it was, says Gaius.

This reminds Victor that, earlier, Terence had mentioned burying Waca.

And where is Waca now? asks Victor.

There, says Terence, No wait, I think it was there. Or a bit closer. 

You should have left a marker, says Camus.

I did, says Terence. His head was the marker.

There you are then, says Gaius. We'll soon find Waca.

Or his head, says Victor, taking out his notebook.

Waca - Missing head.

He adds (seeing his notebook is out now): Gaius- shorts stained - red. 

Stop writing, Victor, says Gaius. Help us find Waca's head.

What does it look like? asks Victor.

Somewhat shiny, being lacquered, says Gaius.  

Laquered! exclaims Victor. 

Glossy, says Gaius. 

You've neglected to say it's a duck, says Camus.

A duck. Laquered. A toy duck. A red herring.

Victor puts his notebook away.

Waca is in fact close by.

He has not revealed his whereabouts for this simple reason.

He is totally buried. 

And Gaius is responsible.
