  Two-Higgs-Doublet Models (2HDMs) are amongst the simplest extensions of the
Standard Model. Such models allow for tree-level CP Violation (CPV) in the
Higgs sector. We analyse a class of CPV 2HDM (of Type-I) in which only one of
the two Higgs doublets couples to quarks and leptons, avoiding dangerous
Flavour Changing Neutral Currents. We provide an up to date and comprehensive
analysis of the constraints and Large Hadron Collider (LHC) predictions of such
a model. Of immediate interest to the LHC Run 2 is the golden channel where all
three neutral Higgs bosons are observed to decay into gauge boson pairs, $WW$
and $ZZ$, providing a smoking gun signature of the CPV 2HDM.
