The Labours of Lord Perry Cavendish. Winterbourne, #4

Lord Perry Cavendish knows that he's seen as a not-too-bright, amiable, sporting sort of chap. The type who can hold his own in the boxing ring, drink most men under the table, and offer a useful opinion on a piece of horseflesh - but not much else.  When Perry visits his friend, Lysander Winterbourne, he is introduced to the Honourable Jonny Mainwaring, a free-thinking artist who is everything Perry is not: unconventional, emotional.  and very talkative.  At first, Perry is overwhelmed by the vibrant, witty Jonny Mainwairing, but when he agrees to sit for him, he discovers the real man beneath the dramatic flourishes, and the undeniable physical attraction he feels for Jonny begins to develop into something more. But Jonny is not to be easily won over.
While he has a longstanding weakness for brawny men like Perry, he's still smarting from his latest heartbreak and determined to change his habit of throwing himself into each new affair without pausing to recover from the last.  Can Perry convince Jonny that he is more than just an empty-headed young buck, and that they could have a real future together?
