Here is another of our occasional "in search of" columns featuring people hoping for a blast from their pasts, along with an update on efforts to help children and parents in international abduction cases.

Briton Alan Saxton is looking for Misako Mori, whom he met in Komatsushima, Tokushima Prefecture, back in 1965 during his time with the Royal Navy. They became penpals and had a mutual friend called Margaret Faulkner. Alan believes Misako is now in her 60s and has since married, but he has no further information.

Also searching for former penpals is fellow Briton Maura Clark. She would like to get in touch with Akemi Yoshida of Yokohama and Mayumi Kasa of Fukuoka Prefecture, both of whom she corresponded with as a teenager in the 1970s. Maura lived in South Benfleet in Essex at the time.
