Found a hand written letter in the pocket of DH's trousers. The letter is written in very fancy writing, it has a name at the top then 3 women's names (exotic type names) with their phone numbers then at the bottom the name of one if the previous women and a mans name (not at all exotic) with a land line number. Then under that the other two women's names and a landline number. Both landlines are local to my area. By one of the women's names he has written a 'D' then by the other women's name 'Sin L'. He has been wearing these pants to do work in the garden the last few days so I know it is recent. Any ideas what it could mean?
