I was searching for this kind of story: a historical setting, nice manners by the main character and a mystery case. :3 
 Percival, short and kind called Ival by his lover Griffin was a great main character. I loved his shy behaviour, I'm totally captivated by his look and his character. :3 Griffin on the other hand is all Ival isn't and so he fits perfectly to him. Both had the special chemistry I love. 
 I almost feared the erotical scenes would be very low but I was wrong. :3 They are totally H-O-T! *^* Damn, Ival knows what he want. *catching air* 
 The case itself was mystery at it's best, with paranormal and spooky elements, I was thrilled and highly entertained. :3 
 Can't wait to have further cases with the two handsome guys. 
 Catherine as one interacting female was a great companion to Ival and Griffin. I really loved her understandment. :3 
 Well develope character, great story with a well presented case and two absolutely charming main character I instantly fell in love with from the first page on. :3 
 Clearly 5 out of 5 stars for this great prelude of the series. :3 I'm so happy to know there are further volumes. <3
