Stuck in traffic, I noticed a woman with a baby on her lap at the bus window. Seated towards the back of the ground floor of the bus, and almost level with us, she was the spitting image of JS. When our queue edged forward, TPR pointed out another identical woman. She was travelling a few seats further forward from the first.

TPR wound down our passenger side window and attempted to attract the attention of the two women. They both waved back enthusiastically, then one confirmed that they both already knew that they looked like clones of JS because we’d pointed this out to them in the past.

“Give them my business card”, I instructed TPR, “and persuade one of them to pass over hers. Then we can ask them to send a couple of photos to be forwarded to JS.”

The women were dubious that we were trustworthy enough to share contact details. “Read my card!” I insisted, “I am a respectable person”. The job title of “professor” appeared to win her over, and soon I was clutching the contact details of one of women. It said that she was a puppet maker based in Bristol. With such credentials, I wondered whether she had ever heard of the Scottish Falsetto Sock Puppet Theatre.
