Summary
Analysis
Billee Bee sends Juliet a telegram explaining that Sidney has been called to Rome and asked her to visit Guernsey in his stead to collect the Oscar Wilde letters. Juliet sends a telegram in reply; she's happy to receive Billee Bee.
Remember Susan's note to Juliet that Billee Bee is too sweet—this suggests that Juliet should be cautious about Billee Bee's intentions.
