I'd had the night off, Catherine was working, and I couldn't sleep, so I'd been reading. This time it was an old John le Carré book about spies and trying to solve the clues to work out which one was the double agent.

There was this scene when the KGB tried to use sex to trap this spy, blackmail him into working for them. Apparently they called it a honey trap. I thought it was badly written, but it could be fun for Cath and I to play out. All I had to do was work out how to give her the clues to get her to act the right way without telling her.

Suddenly it all clicked. OK, I was the physics major, but Cath was pretty well clued up in the all the sciences, she'd get the hang of it soon enough. I prepared a load of post-it notes, stuck them in the right places, then put myself in bed, wearing just a big smile and waited.

I didn't have long to wait, Cath came in about 10 minutes later and called out to me. I didn't answer, and I could hear her moving around, taking her shoes and coat off, before she noticed the first post-it.

"The front door is (0,0)" it said. "With your back to the door when closed, you are facing positive x, positive y is to your left. The grid is a metre on each side. For more instructions go to (3,2)."

Catherine muttered something about not being in the mood for silly games, but by now she knew where to find me and she could have come straight in.

The next puzzle was a bit harder – the card said the x value of the next clue is the area under the straight line between this point and the origin. The y value is the constant acceleration required to make that trip in 1 second.

After some muttering Cath worked out that this meant (3, 7.2) it took her to roughly the bottom of the stairs. More importantly it took her to a position directly under the door to our room. On the newel post was the final instruction. 'Go 3 metres in a positive z direction. Rotate 180º. Say the name of the function using time and claim your reward."

"Velocity?" she said as she opened the door and kissed me.
