Doctor Lovebeads (Asphalt Warrior)

In Doctor Lovebeads, the fifth in novelist Gary Reilly's Asphalt Warrior series, Murph must go undercover to accomplish his mission. He lets his hair go untamed, dresses in muslin and sandals and arrives on the scene in a beat-up VW van called the Cosmic Wonderbus and Mobile Mercantile.
Murph tries to pass himself off as an old love child in his confrontation with Brother Chakra. As the good Brother might say, It's a mind-blowing trip.
