I am one of the Sherlock Holmes' here. I saw my friend Joan had volunteered, and if it is all right with you I am willing to offer my services in first aid. I have had basic first aid training but I also know how to do some emergency services, things a nurse might be able to handle. I can set up IVs and the like. If I am there she will be better at concentrating on whatever injuries are coming in, and she is almost as good a doctor as she is a consulting detective. I know how she worries, though, and it would help her be at top form.
