Mr D at first I really thought this was about a hooker and then it dawned on me what you meant by 'calling card' (it's been a long day with travelling home and the likes lol) this really fascinated me, how you did this and I'm glad to see it nominated.
Mr Darcy you are doing a great job by writing poems about such serious issues. I have seen few episodes on television regarding serial killers and they are the worst people. I can't even describe the things they do to their victims.
I wasn't expecting this content for a poem with such a title, which is fitting because usually people think that people who do bad things seem harmful, which they don't. They can seem all sweet and lovely and have families that they have a great relationship with and still have a dark side. I loved the wording, and flow of the poem. Great write!
