The golden wishbone

Jessica writes:

I live on Drakefell Road and unfortunately I lost a very sentimental necklace charm on my travels this morning. It may have fallen on the train, on my walk to Brockley station or on the train itself. Got the train at 8.22am.  The charm is a gold wishbone. Somehow I haven't lost the chain but just the charm itself.

If someone found it, please email me.
