What did Holmes have to do at st monica's church?

Answer 1

___". . . I lounged up the side aisle like any other idler who has dropped into a church. Suddenly, to my surprise, the three at the altar faced round to me, and Godfrey Norton came running as hard as he could towards me.

___"`Thank God!` he cried. `You'll do. Come! Come!`

___"`What then?` I asked.

___"`Come, man, come, only three minutes, or it won't be legal.`

___"I was half dragged up to the altar, and before I knew where I was, I found myself mumbling responses which were whispered in my ear, and vouching for things of which I knew nothing, and generally assisting in the secure tying up of Irene Adler, spinster, to Godfrey Norton, bachelor. . . . -- Sherlock Holmes, 'A Scandal in Bohemia'
