from Dr J Watson to Sherlock Holmes Esq:
Ah dear chap, I was just ruminating on our last case and how much I enjoyed plunging into the investigative fray. As it happens, my wife is planning a visit to her sister so will be away for a few days. My own caseload too, is somewhat sparse at the moment so I would relish the opportunity to join you in our fight against crime. I shall pack an overnight bag immediately.
Your faithful friend
