Arnold and Beverly owned a large tract of land, Blackacre, in fee simple as joint tenants with rights of survivorship. While Beverly was on an extended safari in Kenya, Arnold learned that there were very valuable coal deposits within Blackacre, but he made no attempt to inform Beverly. Thereupon, Arnold conveyed his interest in Blackacre to his wife, Alice, who immediately reconveyed that interest to Arnold. The common-law joint tenancy is unmodified by statute. Shortly thereafter, Arnold was killed in an automobile accident. His will, which was duly probated, specifically devised his one-half interest in Blackacre to Alice. Beverly then returned from Kenya and learned what had happened. Beverly brought an appropriate action against Alice, who claimed a one-half interest in Blackacre, seeking a declaratory judgment that she, Beverly, was the sole owner of Blackacre. In this action, who should prevail? 
Alice, because Arnold and Beverly were tenants in common at the time of Arnold's death.  Alice, because Arnold's will severed the joint tenancy.  Beverly, because the joint tenancy was reestablished by Alice's reconveyance to Arnold.  Beverly, because Arnold breached his fiduciary duty as her joint tenant.
