Sir,
Theft from St Mungo’s Blood Bank
40% of vampire blood reserves were removed between 6pm 11th February and 8am 14th February.
Notified this morning and am on site as I send this communication.
Senior St Mungo’s staff regret to inform their records have been tampered with and the supplies are unaccounted for.
Given the appearance of the missing students is office gossip this morning, this may be of significance.
I await your return.

Head of Being Division
