While in cruise flight; I began to notice undesirable engine trends and indications of an impending failure or forced shutdown. I adjusted my destination from ZZZ to ZZZ1 with ATC. Upon further evaluation and worsening engine indications; a change of destination from ZZZ1 to ZZZ2 was requested with ATC and approved.As I turned toward ZZZ2; I was forced to shut down the ride engine and requested priority handling with ATC. An approach to land was made on Runway 13 with no event and no injuries to passengers or crew. We then exited the runway and parked at the FBO as if it was a normal flight. I then contacted WX Brief and asked them to contact Center; relay my phone number; and confirm I was safe on the ground. Center Controller then contacted me to verbally verify we were safe on the ground in ZZZ2. I would like to thank the professional and extremely helpful Center Controller. It helped in a truly troubling situation.
Beech F90 Captain reported diverting due to deteriorating engine parameters which caused an in-flight shut down of the right engine.
