As the other man entered and addressed their hostess Miles took the opportunity to size up the man. Rich upperclass, pinched, pressed, and shined from the crease of his cuffs to the toe of his shoes. Outside these obvious trappings, the man was plain looking enough- but there was something about the glint in his eye that set the Detective in him on edge. 

This man, Spencer Cole, had something sharp and hard in him- not junkyard dog mean that would rip and tear, but something colder... Miles wasn't sure he wanted to find out exactly what kind of mean Spencer was. 

"Likewise I'm sure," he said in response to the man's greeting and taking the man's hand in a firm grip. Miles hadn't heard of this man before this moment- frankly he hadn't been aware that this was a 'group' enterprise in the first place. And while this cast some considerable doubt on exactly what kind of case this was, he was certain this other man was just as clueless as he was. Miles could tell a bluff when he saw one.
  
"And it's Detective, actually." He continued, casting a glance at the Pianist with a slight nod to show no hard feelings at the slight faux pas. He wasn't some vagabond off the street, however he might look like it- or how tenuous his employment may be, he wasn't going to let it go until they took the badge from his cold dead hand.
