I need a logo designed

We have developed a live escape game called Escape Live. It is a series of physical rooms where teams of 3,4 or 5 people go and spend an hour solving puzzles, unlocking locks, putting clues together in order to get out within 60 minutes. One room is called Dr Wilson's Office and we need a logo for Dr Wilson's Office. We want to try and keep the feel of the logo very Sherlock Holmes (detective, spy, clues, problem solving) and one of my competitors uses the attached logo which we really like. The key focus in the logo design is the wording "Dr Wilson's Office". We are thinking a character such as the one attached and the wording over the top or underneath him? We can't make the logo too similar of course so i'm just forwarding it as an example that we really like. It's the file called keyhunter. to see their website visit
