Atomic Lobster is the tenth novel by Tim Dorsey.
[1] A chance encounter leads to the traveling duo of Serge and Coleman picking up a third member, a drug-addicted stripper named Rachael who reminds them of their late associate Sharon, and the dysfunctional group becomes involved in house-sitting, Serge hijacking support group meetings, and a reunion with Serge and Coleman's old neighbors Jim and Martha Davenport.
A mid-life crisis, their daughter's engagement to a vacuous rich man, shady movers, and their own justified wariness of Serge all weigh on the Davenports, but Serge may also be their only salvation against the vengeful cousins of some criminals Serge and Jim killed in the third book and a group of smugglers who eventually become convinced that Jim is a dangerous secret agent who they must kill.
