A request came for you directly. It looks like an information-gathering job. It's an important request made by the Adventure Guild Master in London, so you should go and get the details from him in person. Rumor has it you're very capable indeed, so you should have nothing to worry about.
Note: This quest appears requires that you have discovered Siberian Husky before it can appear and cannot be shared with those who have not done so. Alternatively, it can appear at Stockholm Adventure Mediator for all players and also in London if you've discovered Xanadu as well as the Siberian Huskie. Stockholm is obviously quicker and can be shared with others easily, though -- the only difference with taking the quest from Amsterdam/London is a few lines of dialogue.
Thanks to Ledodu for some of the original guide info.
