Michael Baigent RIIP,

The Deaths in 2013 site lists under June 19th, the following:

 Michael Baigent, 65, New Zealand author (The Holy Blood and the Holy Grail), brain haemorrhage

There was a previous suggestion of "blood" after all.  In this case "Blood" in the title of his book and Michael's death from a hemorrhage, the first part of the word coming from Greek "haima" meaning "blood"... audd how similar "haima" is to "home"... especially the root origin, note the etymology:

 home (n.) Old English ham "dwelling, house, estate, village," from Proto-Germanic *haimaz

hemorrhage (n.) ...from haima "blood" (see -emia) + rhage "...to break, burst."

Michael's inner twin was involved in their conjoined deaths of that I'm quite sure, butt rather than just spell it all out as usual, I made up a little verse with cryptic clue's that help you follow the leads:

There's more to a name than the sounds that we hear,  

so when you see the stone the path becomes clear. 

Though big and scary it may first appear, 

when set in reverse it's nothing to fear. 

At the top of the tree it's now time to veer,  

and turn back to the place beside the two spear.

With the quick circle of knowledge and a steady peer,

one learns more of this place in the digital sphere. 

Though many a cat regularly appear, 

 hope for a better life is the one to hold dear. 

Another cat awaits to which you must steer,  

a reminder to shake off slumber and guard at the rear.

A midst a pine forest there's a triangular shear, 

encompassing a park with the highest tech gear. 

When someone responds in the comment section with the right answers to the italicized clues, I'll give my Tou sense worth.
