Storylines
Len is a man who unknowingly helps Shirley Carter and Heather Trott to steal a car that Pat Evans borrowed from Kevin Wicks. As Shirley and Heather drives away to Brighton, Pat comes out from the service station and calls out that it is her car, but she slips and breaks her shoe. Len mends her broken shoe, and then offers her a lift to Worthing, where she had been heading for.

After Pat accepts, he drives her to a run-down mental facility where Pat's long-lost sister Joan had been sent sixty years previously. After being refused entry, he helps Pat to break in, where they discover that Joan hadn't died aged 22 as Pat had been told, but had been sent to a different hospital in the 1980s. However, while running from the police, Len drops the paper which reveals which hospital she had been sent to, but he searches the internet and finds the location. He takes Pat there, where they discover that Joan had only died a few years ago, and that she had married in 1963. He takes Pat back to Walford, where he says goodbye to her, giving her his card, looks around, and then drives away. Len isn't heard of again until Christmas Eve 2007, when Pat receives a rocking horse and card from him.
