In the episode The Sign of Three (S03E02), Sherlock remembers that Tessa knew John's middlename and this is how he figures out the whole thing about the Mayfly Man and his attempt to assassinate one of the guests.

I didn't really understand the connection between him dating the women and attending the wedding. I mean, he was the photographer, so he did not need a date for the wedding. And if Tessa was not invited, but only saw the photographer's invitation, why would the killer need to date those women?

So, what was the purpose of dating the various women?

1 Answer 1


He was the stand-in photographer, implying that, having discovered that his target was to attend the wedding he put things in motion to ensure that he would be there.

The women were all employees of his target. By dating the women, he was trying to find some information about his target that would enable him to carry out an attack.

Tessa saw the target's invitation, not the photographer's. She evidently let some details slip to the Mayfly Man. Perhaps some ill-considered pillow-talk.

    @Dredd IMO this episode is very weak with logic and connection. Return to the topic SH said that all women had some secret which was working for Sholto. So MayFly choose all women because of their employer. Jan 9, 2014 at 18:17
