Alice has problems
with a private affair;
talking to Bob
without Eve being aware.

For Alice loves Bob
He has the key to her heart.
But then so does Eve
and she wants to keep them apart.

To keep their secrets
they must find a way
to communicate in public
without Eve hearing what they say.

A public channel
with a private communique.
How to solve this cipher
so they can communicate as they may?

They need to cut through the spin
so Eve can’t interfere.
Eve loves Bob and hates Alice
There’s a polarity problem here.

They cannot do what they used;
when they’re apart – a call.
Now they talk by coded waves
with no privacy problems at all.
